Hi everyone,

Just would like to get some clarification on what i would need to convert my 96 TE magna from manual to power windows.

from reading other threads I have realised i will require the following:

- door trims/ speaker pods
- regulators
- power window swtiches for each door
- in door power window harnesses

what i am a bit unsure of is what i would need in terms of dash harnesses. If i were to get these items from another TE that has power windows is it a matter of replacing my existing in dash harnesses or do i need to do some additional wiring? if so what needs to be done?

my TE has factory cruise control, i have heard this simplifies some of the wiring?

I have the same question, bumping for a hopeful answer :).

I wanted to do my TH but the guy at Magna Wreck said if i went with stock magna power windows Id have to change the ecu..didnt have to if going aftermarket.
A friend who owned a tinting business said the only aftermarket units worth looking at were about $800 per door... :/

Shouldn't have to replace the ECU, It doesn't control the power windows, the master control switch does.

Should just be able to replace/rewire the wiring loom, just not sure what needs to be replaced.

this is the 3rd or 4th time ive had the information told to me by the guys at magna wreck contradicted on this forum...im beginning to think magna wreck dont know what they're talking about?? :/

Ecu doesn't need to change.

No ECU replacement needed, some of the models come with a floor loom, included in all the wiring, however some do not, If it does not have the floor loom I think you will find that you need to replace the behind the dash loom with a model that does.

I would also like some more light shed on this because I doubt it would be a simple swap of a TE Exc Loom (Which does not have the floor loom) and say a TH Sports Loom (Which im pretty sure does.) If it is a simple swap though it would be a very very easy process.

I'd imagine if you had a similar verada or a magna with power windows, it'd be a straight swap with door & floor looms, door window switches, door regulators & runners, fuses/relays. ECU would only need to be swapped if you changed the engine (plus dash & engine looms) as well.

Otherwise, it seems quite easy to make the power system work with the standard exec loom, looks like you will need to plug a few wires to pass through the fusebox and BEM (if the car has one).
For example: Checking the service manual for a TH power window setup; there's two wires in the loom that goes into the engine bay fuse box; one coming from the BEM (Pin 28 blue & yellow wire) and the other from the drivers side power window switch (Pin 2 blue wire) to the fuse box in the engine bay, where it is then connected to a relay and then to battery power.

edit: ↑ Above advice is for BEM model magna's.

OP - Personally, I think you're best option would be to find a KE/KF Verada or TE/TF sports wreck (either from auctions or wreckers) and basically re-shell your current one with the verada interior and electronics.

sounds complicated - think ill go aftermarket...

edit: Refer to next post.

Previous post was regarding bem model magna's.

Sounds to me like magna wreck are a bunch of dicks

If an exec main cross loom and both floor looms need to be changed. Was not until some of the later th that the wiring in the main cross or dash loom was there but not used

Te and tf will require these in exec form, advance only needs rhs floor loom in advance. Alters has fast glass anyway

Also please ignore above post as te and tf don't have a bem, if you use verada loom no need to use verada ecu either

ok forgive me but im still a little confused - are you saying that on a 2000 TH exec you dont have to change the ecu? I dont quite understand about the different looms....

So on my TE Exec i can use the looms from a KE/KF TE/TF that has power windows and all i would need to change is the cross(is that the same as the dash loom?) and floor looms? and it would be plug and play except for running the extra wiring into the engine bay for the relay/power?

No extra wiring. Engine bay only needs relay installed in front box. Place is there already

Im thinking of going down this road - the guy that re gassed my AC told me about it & says he's been using them for a long time with little problems. He's not trying to sell me a unit he said i could get them online to save money...

Its been a while but I found a TE Altera. Planning to take everything from that car and transplant into my TE Exec for power windows, Which loom is the cross loom?. From Altera to Exec it should be all plug and play correct?

Correct. You need the door looms and floor loom. Pull out the interior and carpets and the loom that runs across the floor is what you will need. Pillars need to come off too.

Keen to see how you go as I'll be attempting it in the next 6 months.

update - pulled everything i need from the Altera I think. I pulled all 4 door looms with regulators/motors. I pulled the driver side floor/cross loom as well. I didnt pull the passenger side floor loom which plugs into the cross loom - do i need this?

only reason i didnt is that i checked the plugs that go into the passenger front/rear doors and they seemed to have all the extra pins required, so i assumed they were cabled?

Any chance you could take a few pics of your progress ?

Going to attempt this once I find the looms & door cards (already got the regs & switches)

I'll be watching this one with much interest too ;)

ok update. in ,my last post I said i only pulled the driver side floor harness. turns out i needed the full thing so ended up pulling the whole thing.

I spent the weekend putting all the gear in. I can confirm for a conversion you will require the following:

- floor/cross harness from a model that had power windows
- door harnesses
- regulators/motors
- power window switches
-speaker pods(the power window door trims are a different shape)
- door trims
- engine bay relay (just pop it in)

once you have all of the above its all plug and play. although it will require you to remove seats,carpet to run all the wiring(you even have to go underneath the car as the harness extends under via a grommet). removing/installing regulators can be a bit tricky as the space in the doors is tight and once you unscrew everything the glass tends to fall.

will post pics soon

So did you need to get the dash loom from the Altera at all? I have 96 TE Exc aswell but I was pretty sure to get the floor loom I needed the Altera dash loom, can you please confirm this?

Thanks in advance, its either I do this or just do an aftermarket install. Pictures will also help alot.

yea i thought i would require a dash loom too, but its not needed as the dash loom contains none of the bits for power windows. I found this out from looking at where the door looms from the front 2 doors go into and tracing it back. they plug into the floor looms only.

the floor loom on the drivers side has 3 plugs which plug under the driver side dash - undo them and pull the floor loom.

on the passenger side under the dash near the door, fold back the carpet and their will be 2 plugs, undo these and pull the floor loom out from their.

these 2 looms connect under the passenger side seat vai a plug.

to reiterate - no dash loom is required. only floor + door looms

will upload some pics tomorrow

Excellent thank you, will anxiously await pics, sounds like its easier than I thought. So you didnt have to remove the dash to get the floor looms? Did you need to remove the dash to fit it all? How did you go about getting the wiring through the door grommet?

This is awesome!

When I get my TE back from the shop I'll be purchasing the other bits and pieces I need for this.
Other than the door looms and the loom that goes across the floor at the front, did you need any side looms?

haha well i wouldnt say its easy, pulling the loom was quite a task(my hands got quite a few cuts) but yes very doable.

the dash doesnt need to be removed, just the dash covers under the dash on both passenger and driver side(the covers that hold foot lamps).

on the drivers side you will need to undo the bolt that holds the fuse box as one of the plugs you need to undo is behind the box(connected to the fuse box), the other 2 are in the same area above the fuse box, you should be able to squeeze your hand in and undo them. They are located on a metal bracket which you can undo.

on the passengers side, just peel back the carpet, you will see the floor loom go into 2 plugs connected to a metal bracket.

so pretty much 3 plugs on driver side, and 2 plugs on passenger side and the floor loom is unplugged from the dash.

the door grommet is a little tricky, for the front doors use a screw driver to get the grommet out(tight space). pull on the wires a bit and you will see a plug. undo it this will separate the door harness from the rest of the car. its just a matter of undoing all the clips that hold the harness to the door and pulling the harness out through the door.

for rear doors, undo the seat belts from the bottom of pillar B, then undo the lower pillar B. you will see a white plastic seal, undo it. then there is plug that connects to the rear door harness. undo this then the rear door harness will be free. same as the front doors, unclip everything then pull this through the door.

in short you dont need to pull anything through the door grommets, as it unclips at the doors.

Note: for the front doors you dont need to worry about replacing the plug/harness that connects to the door harness, odly enough it has all the extra wires for power windows. for the rear doors this plug that connects to the doors is apart of the floor harness anyways.

get a aftermarket electric windows they hook to where ur manual winder goes and yeah ill link u to a video of them installing one if u wish

Might car mods have done this just recently, however since Magna's already have the option for power windows if you can do this job it will work out much better, you dont have to worry about stripping any gears if you buy a cheap kit and you get to keep everything factory. I was thinking about going down the aftermarket route but the issue with this is with most kits its a hit and miss whether you can use the factory Magna door switches, so to keep it semi factory you would need to cut the factory switches out of the door card, glass a backing where you removed the switches, bog it flush and then cut new holes in the power window switch plate to install the aftermarket switches.

haha well i wouldnt say its easy, pulling the loom was quite a task(my hands got quite a few cuts) but yes very doable.

So just to clarify for anyone who digs up this thread, you have the Executive with no cruise control?

When I do it I plan to only start with doing the front two doors anyway, I just need to find a TE P/W Trim that is dark grey all over instead of Dark Grey ontop and Light Grey on the bottom. They are alot harder to find than I thought.

My TE does have factory cruise control. Sorry should have mentioned this.

posting pics as promised.

these are the harnesses I pulled from the TE Altera. The one on the left is the driver side.

this is the driver side harness laid out next to the car so you can see how it runs. Note it goes all the way to the boot and connects to the tail light harness and contains the wiring for the speakers/bootlight.

Photos look great very handy however I would like someone to confirm but I believe if you don't have cruise that means you need another dash harness? Correct?

It depends on your model and possibly manufacture date. From my understanding and for example and for the sake of discussion, my TH is a pre-April 99 build and as such doesn't have CC wiring to the engine bay etc, but had it have been post-April it would have had this wiring, I believe.

What model and build date peaandham?

Mine doesn't have cruise, if no one else does it by the time I get round to it I'll let you know.

TE Executive, cant check build date atm, but with no cruise I think ill find I need to swap out the dash wiring if I went down this path.

Yeah I dare say you'll be swapping the harnesses. At a guess it would be the dash harness, and not the cluster harness (unless you're putting in cruise etc)

Which part of the dash wiring?

I am thinking about doing this as well your photos are very helpful in giving some idea as to what may be involved. My car is a Th so I am still a bit unsure as to the wiring side. I guess when i try it I'll just have to follow the wiring from the doors back to were they start. I'm sure were these looms from the doors plug in to the existing wiring. Was also surprised to see the wires going back to the boot but I guess it makes sense as you have door speakers at the front as well as the ones at the back.
It should be hard to find the parts for this job - assuming you can get in early and find the full set of doors. Many wrecks i have looked at aready have one door trim gone or the trim is pulled of and one motor etc has been taken.
How much is this project likely to cost assuming you are using parts from a wreckers? It was suggested to me it might be cheaper to buy complete doors (correct colour coded) but this will cost around $400 and I haven't found any car with the same colour coding. (Being a silver TH (pewter) it means earlier silver models are a different colour). What ever the expense I think this will be an awsome progect and I think I will start collecting some of the parts that I will require.
