Good evening all ......

Being the hero that I am, when confronted with the question 'Do you know anyone who can install a kenwood in my magna?' ........ I replied with 'My friend, I will do it for you!'

Big mistake. Now I got drama's big time.

Pulled it all apart, pulled the unit out. Now I unplugged the connector from the stock Magna stereo (99 model Magna, standard magna I think) ..... but there were TWO connectors, the main wiring connector, and a little plastic connector which plugs into the middle of the unit, running off a single blue wire ...... I cut this off too.

Anyway, after blowing a fuse or two or three, I earther the unit to the chassis behind with a bolt. I put power to the thick blue magna wire, battery to the red stripped etc, just what I saw in a schematic supplied in a different thread (I only saw the schematic AFTER the install, i.e. 5 minutes ago haha).

I plugged up all the speakers, no problem.

OK. So the unit is working fine. Now here are my problems:

1. The hazards dont work. I simply unplugged the hazards when we pulled off the console surrounding the stereo, and replugged it at the end. Nup. If you sort of half depress the hazard button, they work. I am thinking this is a problem with the switch that COINCIDENTLY stuffed up, i.e. maybe its internal contacts are loose or whatever, and a bit of jiggling stuffed it up. Now because the hazard switch is screwed, the blinkers wont work!!!

2. What in Gods name is that single blue wire that goes into the centre of the original stereo?? I cut it off and taped its end off.

3. What in Gods name are those OTHER 3 wires that go into the original mitsu connector? There was 8 for the speakers, ignition, battery, that makes 10. Then there are 3 more PLUS the little blue one as mentioned above.

4. when we yanked off the console, upon putting it back together you couldnt turn the vent selector around to blow in your face. It turned out to be the wire that the switch pulls, to alter air flow. We cleared it off its obstruction, but of course, no air comes out of the face vents now when you turn it on that setting. What in gods name did I do??

5. While the car was off, and we were doing all this mucking around, there was some irregular offbeat clicking sound coming from inside the motor, while only accessories were on. What could that be? Am I at fault for this???


Summary: I learnt a big lesson. Dont help any Tom Dick or Harry and try to impress them with your skills, when obviously you dont know squat, i.e. me.

Now I have the headache or wrecking the internals of this guys car, and he is pushing me to fix these things, when I dont have a clue.

PLEASE HELP ME OH PLEASE. Can someone help answer these questions. If I ever needed help from the net, now is the time. I will be checkingfor replies in 5 minute intervals.

Thank you in advance from the bottom of my heart for your help. Thank you.

Dave.

if it was me.. id be biting the bullet and giving the guy the money to take it down to a proper installer to fix the work.

I feel your pain.. i encountered problems when doing my install in my first car (a TR magna) i eventually sorted everything out myself after about a week and completely fluking it in working out what was wrong.. but yeah as a rule i just spend the money and get a pro to install everything for me now!

Ok, The spares you have are :

Mute wire (for Mobile Phone) - This is the blue wire i believe.
Rheostat (for dimming radio lights with dash) - This is black/yellow i beleive.
Backlights (turn on headlights turns on radio backlights) - This is green/white i beleive.
Auto Antenna wire - This is pink i beleive.

PM sent thank you :)

Ralliart, I figured that they would be related to dimming etc.

He does not have a power antenna (thats what he told me anyway).

If I left them unconnected, that wont affect anything will it? I figure the unit just wont dim when you switch on the lights.

Or am I wrong and have stuffed something up????

That blue wire with its own connector worries me heaps, it seemed important to be on its own with its own connector .......

Thank you for your response, all of you!

The thick blue wire is the ignition wire. This needs to be switched (if you want it wired properly). The colour of the cable which has full time 12v is red/black and it should be slightly thicker then the others.

Just tape up the rheostat, mute and auto antenna wires and you should be fine. Forget the single blue wire. It is of no use unless you have a phone car kit installed.

I would say co-incedental. If you were a bit rough with it you could of easily damaged it. Easy to replace it. Oh, no hazard switch = no indicators either (checked circuit diagram)

For a test pull the connector out from the switch and short out pins 5 & 7 in the plug. This will allow current to pass into the electronic flasher unit and blinkers will operate as normal.

Do you understand the wiring above?

yeah i remember hte same problem in my vehicle (Nissan Pulsar), no hazards, no indicators.

I think I will replace the switch from the wreckers or whatever. ........

Anyone know where I can get a switch from a wrecker in Sydney, and how much it would be????

hey mate, i think your wiring for the headunit seems fine, but with your indiators, if the hazard switch is stuffed, then no indicators.

I have had issues regarding buttons before.my air con button died when i was installing it. It probably has nothing to do with u, so yeah, buttons die for no reason sometimes. Also, I tried to remove the hazard switch out of the console, but it was imposssible :rant:

some people have done it before, so yeah..good luck with it.
oh, yeah, a rule i have when installing stuff for my mates is if i break it i pay for it. simple

hey eek

oh yeah i am all for it, if i screw it up, i am going to fix it, no questions asked.
Thanks for the help

Just came on here to see why are all these things happening???

So We have worked out a few things. The switch is *probably* stuffed (hazard). So I will replace it. The wiring is cool. Thank God.

So can anyone help us with this crazy clicking sound that was happening in the motor? Literally, the accessories were on that was it, no radio playiong no nothing, there was just a constant, iregualr clicking sound.

And secondly my vent drama?? Like I said the switch couldnt move to the fact mode, when we freed the wire conected to the switch, it could turn fully onto each setting. Now however, no air comes out of the vents on the dash board for your face etc. Can someone help me there??????

Thank you!!!

i assume you're talking about the big dial on the left of the console, next to the hazard switch? u can turn it to the 'blow in face' setting, but no air comes out of the vents? does air come out when its on teh 'blow in face and foot' setting?

check all the cables it pulls behind the dial and inside the dash....could be the vents giving u trouble. :confused:

yeah I had similar problems, but I managed to figure out what the extra wires were by wading slowly through the schematics in Gregories.
I also have the air vent problem. Now the air gushes out on the drivers feet and only trickles out the face vents no matter what you turn the dial to!!! I havent had time to try to pull it apart again and figure out whats gone wrong.
Yes the little blue wire and connector are for a mobile.
Cheers

Yeah. I can turn the dial like normal though, but it doesnt change the air flow out the vents.

The vent problem I think is caused by you pulling an (actuator) cable off. If you take off the panel unde the steering wheel you will see a white cable end that goes up to the vents. This is to the left of the brake/clutch pedal it is relativel high up, make sure you havent dislodged this cable from the puller. Sorry for the bad terminology.

further to what Green Matt has said, if a vent or heater control cable is not in the retainer clip correctly at the heater box or the outr of the cable has moved in the clip then it may be out of adjustment. This can cause the dial to move with normal resistance but the lever at the heater box will not move through it's full travel and select all positions, usually it's the face vents that don't work but u can still switch between floor and demist.
