Posted: Tue Feb 09, 2016 6:12 am Post subject: Can I add cruise control and how big project? |
|
|
I keep seeing people selling the steering wheel stalk controls (wipers, signals, cruise) from 944's. As my 88 924S is an auto and I do frequent freeway driving it gets me wondering how hard it would be to install cruise control from a 944 to mine. I'm not the best wrencher but I have a decent mechanic. Anyone have any thoughts or ideas on this potential project? I assume I need a deal more parts than just the control as well?
Thanks for any input. _________________ 80 931 <RIP - Change your Timing Belt!>

Cruise control was an option on the 88 924S, so it is highly likely that the fuse block is already "stubbed out" for it. The question will be, can you identify and surgically remove all of the required wiring elements from a donor car to graft into your existing car.
I would suggest getting ahold of plyhammer or dimi or one of the other guys on Pelican / Rennlist who regularly dismantle 944s, as they are most likely to have all of the pieces you need. The one thing you might run into is that the 924S retained the early fuse block, while I believe its contemporary 944 siblings would have had the updated under-hood fuse block. This might make sourcing a setup more challenging.
The easiest option would be to source bits from another 924S, but I've personally never seen a 924S with cruise even though it was an option. If that fails, I would then look at 1985 944 as being the best chance of being directly transferrable, as I know the 85s had cruise as an option and still had the early fuse block and old-style dash and steering controls. _________________ erstwhile owner of just about every 924 variant ever made |

As ideola said, cruise was an option. My '88 924S has factory cruise. However, my '87 924S does not, but I do believe that all the wiring is there, so check with those guys to make sure. From what I have seen you will just need an early 944 stalk, brain, and controller. There is also a switch that you'll need for the clutch pedal. I also have cruise on my late 944 and most of that stuff looks the same, so it might also work.
I hope that helps!
EDIT:
Here's a pic of a 924S with Cruise. I forgot to mention that there is something that connects to the accelerator pedal that you will need.

Thanks for the info guys. Just to verify, for the stalk controller I would need one from a 924S or a 85 or earlier 944? _________________ 80 931 <RIP - Change your Timing Belt!>

The stalks for the 924S and early 944 are the same. I should have wrote "early 944/924S" but figured since cruise was so rare in the 924S that sourcing an early 944 stalk would be easier...
I hope that helps!
EDIT: Here's a picture of the stalk in my 924S. Again it is the same as the early 944. The stalk in my late 944 is on the other side or the steering wheel and completely different.

I've used these on other cars, and they do indeed work great. I also went a similar route on my '87 924S. The cruise control I used was a new in the box unit from the late 80's, but wasn't really any different than the modern ones. That said, with aftermarket cruise controls you often have to fabricate brackets and might even run into issues where a lot of other parts may need to be fabricated. Something he won't have to worry about if he uses the factory equipment since it all should just plug in.
Here's some pictures of the aftermarket cruise in my Turbo 924S.
I hope this helps! _________________ '84 944 -White, Brown interior

I think i've sourced the parts! From an early 85 944. I need the control, the servo, the "brain", something that goes to the gas pedal, a cruise control cable... Am I missing anything I should request of the person removing it from their 944? Does it have/use a Relay? _________________ 80 931 <RIP - Change your Timing Belt!>

I'm trying to find a diagram for the cruise control, but am coming up short. Sounds like you've just about got everything but the clutch switch. In a week or so I'll probably be working on my cruise control in my 924S to figure out why it only works intermittently. I'll let you know then, if you need anything else.
The only car I have on hand today with cruise and is a late 944, but it uses the same accelerator bracket. It had been a while since I had been under the dash so I forgot exactly what was needed, but that golden bracket is what you're looking for.
To anyone else reading this.... even if you are thinking about installing an aftermarket cruise control I would also recommend getting this bracket and connect the cable here instead of the throttle cam. If you connect the cable to the throttle cam instead of this bracket, the accelerator pedal won't move and you can actually tangle the cables together as the pedal cable slacks! Causing a very dangerous situation that could potentially cause a wreck and even engine damage.

Do I need a "clutch switch" on an automatic vehicle?
