How do I install genuine cruise control on a vs executive?

go ask holden
The vp's had a genuine aftermarket accesory loom that dealers could fit, maybe vs has some thing similar.

I've seen cruise looms on Ebay recently - maybe they are too old to stock at Holden and they sell them off to outsiders who then on-sell as NOS.

ill have a bit of a look over the car today or tomorrow and try to sus it out, i just bought the car off a friend and im pretty sure he said it had an aftermarket cruise installed, but it doesnt work.
would this be helpful? could i simply replace the aftermarket parts with the genuine parts?
and I'm guessing this aftermarket one would have a break switch, (bit of a stupid question) but where is it?

The aftermarket one probably uses the existing brake switch - the genuine one uses an extra brakeswitch so that if one fails the other one works.
You will not be able to swap parts from genuine to aftermarket as they both use different modes of operation - the aftermarket one probably uses a vacuum servo to drive the throttle whilst the genuine uses a stepper motor driven by the ECU so the genuine one is much more 'sophisticated'. I'll take some pix later tonite of what you need to do to the car like relay and brake switch etc.

Thanks, that would be greatly appreciated :yeah:

Here are some pix - they should enable you to decide if your car has the plugs etc and where some of the bits go. I reckon if it has the plug in the engine bay the rest will be there.
If you get a brake switch from a wrecker make sure you get the clip for it as well which adapts the switch to the pedal box.
Good Luck.

If any of you blokes decide to fit cruise you may find the following tips useful:
1...when you remove the CC brakeswitch from a wreck unscrew it...don't simply pull it out and also get the spring steel adaptor that the switch screws into - use a pair of long nose pliers or a small flat screwdriver to prise it out.
2...If you buy a secondhand indicator arm get one that still has legible writing on it as this indicates lower mileage and a better chance of it working.
3...Ensure any parts you buy are from a VS...this avoids having to "make" something fit.
4...the relay can be any small relay from a VS.
5...be careful clipping in the CC module throttle cable as the plastic can get brittle...make sure the one you buy is in good order....also try and get the bolts that attach it to the inner guard.
6...when fitting extra brake switch push brake pedal in and hold, insert switch and push in till it goes no further and then allow brake pedal to return - you will hear it pushing the switch back (maybe you will need to pull the pedal back to its position).
7...make sure brake light bulbs are working (CC senses bulb out)
Good Luck.

hey markovr,
yeah if you could dig those up that would be awesome!
i had thought that i might already have the wiring there but without knowing exactly what i was doing i didnt wanna go digging around.
thanks alot, hope you can find it

Here it is..a little large and its for a vr...vs has a different v6 engine throttle bracket and its bcm/keyheads dont need changing and it uses a half size relay in a spare spot above the fuses for it

 

[Ryan272]

thanks very much for that, your a lifesaver!
is that the sort of thing i can find in a workshop manual for the vs? 'coz that'd probably be something worth looking into.

i now have;

- cruise module and throttle cable
- indicater stalk w/ cruise
and
- brake switch and clip.

that's all i need to begin installation yeah? that's supposing the wiring is in the loom on the passenger side.

You'll also need one of those small relays in the second picture I sent.
The diagram that markovr posted I'd imagine is dealer only info as it refers to retrofitting cruise to VR models using a patch cable whereas you are fitting it to a VS without a patch cable.....basically 'plug and play'.
When you plug the cruise module in make sure the connectors are clean - mine were full of dust etc and needed cleaning with a toothbrush and solvent. Also make sure there is no way the cruise module throttle cable can come in contact with the exhaust manifold as someone on this forum had that happen - result was a wide open throttle when the cable melted.
