I've decided I might install cruise control on my '99 TH Magna Executive. What is involved in doing so, eg taking apart the dash, etc. How much will it likely set me back? And where can i get it done?

Cheers guys.

It is a fair bit of a job. There's alot of parts that do need to be replaced to have a factory system installed. Alternatively you could opt for an aftermarket system would be considerably easier.

From memory you will need:
- Brake Switch
- Cruise control ECU (small tin box located near the shifter)
- Steering wheel clock spring & cruise switch. Potentially new steering wheel or at least steering wheel backing.
- Vacuum pump on drivers side under windscreen air intake
- Hoses
- Cruise control Throttle body
- Cruise control relays & fuses.
- Engine bay loom
- You may also need to change the dash loom as the loom may not have the wiring for cruise. You can find this by searching or looking through the wiring diagrams on http://www.lisho.net/?page_id=3. If you have a 3.5L model then you may be able to use the KH VeradaEi loom (this will give the opportunity to upgrade to power windows, climate control etc down the track as well)

Mal (Mitsfix) sells Cruise control kits so contact him first.

In the TH, the dash loom does not have the required wiring, the TJ does but few of them did not have cruise anyway

You would need the above plus the main dash harness, all would have to be only out of a TH or KH (adding climate then as well lol) as the J loom is not compatable with the H front harness

I'm assuming those requirements are for installing the factory cruise equipment?

If I was to buy one of these: http://www.ebay.com.au/itm/Cruise-Control-AP150-Command-/150700364236 It'd just simply be plug and play (with a couple of screws)?

Would it be wise to buy one from Ebay and get Mal to install it? Or Just get the whole thing done by Mal? How much are your Cruise kits and hourly rates, Mal? :) or inbox if you like to keep those figures private.

I've fitted AP50 cruise units to a few Commodores and Falcon with no dramas. Worst bit is a half hour under the car strapping a magnet on the propshaft (driveshaft in FWD). Anyone with average mechanical and electrical aptitude should have no trouble fitting one in a few hours. The units I fitted all worked first up with no problems but I must admit I took my time. The AP50 just has a touchpad that sticks on the dash - nothing fancy but only cost about $200.

At that price I'd opt for a factory installed system - it wouldn't cost you much more. Never really been a fan of an aftermarket cruise control system - I've heard plenty of cases of them failing and most of the time this happens when the throttle is wide open.

From memory Mal charges around $250-300 for a complete kit. Which is still almost $100 cheaper than the dodgy & ugly aftermarket system. Since you want a professional to do the conversion then you're still better off from buying the gear from Mal.

You may want to also consider doing a climate control conversion while you're at it. To install the factory cruise control system you will need to have the dash out so you might as well spend a bit extra and get the awesome climate control features as well. If Mal has a kit then you could buy it from him or you would need to find a KH Verada Ei and pull out all the climate control bits (3 servo's & associated shafts, dash & instrument loom, evap box sensor, water temp sensor, interior solar sensor, outside air temp sensor [not necessary but can be handy] climate control unit & breather tube w/mounting bracket) as well.
