Adding cruise control

[porschemech]

Hello all
I am thinking about adding OEM cruise control to my 1984 944 without it.
I have access to an 84 944 with OEM cruise control with what appears to be all the parts in place.
I do not know if the system works as the car is in a salvage yard.
Has anyone ever performed this addition?
Is the existing wiring in place from factory and is it just a matter of plugging everything in?
The car has the turn signal switch, unit on r/h firewall, and I believe the control unit in console.
Is there anything else I would need other than the obvious attach hardware?
Thank you

Is there an unused round seven pin connector tied up somewhere in the engine compartment on the right fenderwell in front of the battery compartment? If not, your car was not wired for cruise control.

I'll add that the cruise control on these cars wasn't the greatest to begin with, and most have failed by now, requiring re-soldering connections in the cruise control module and/or fiddling with the position sensor in the engine compartment servo. I went through mine and got it all working, and it failed again within 8 months.

Other than the cosmetic side, an aftermarket cruise control might be a better solution if it has the bump-up and bump-down capability of modern cruise controls (the factory one does not.) If you go this route, make sure it can handle a manual shift car, it needs to disengage while shifting.

there might be aftermarket kits. here is an example :

I installed one on my old volvo years ago. It has a ton of wiring and sensors, fuel flow sensor etc.
so it would tell me the MPG at any instant or do things like tell me how far I can go with the fuel I have left.. I had fun driving around watching my mileage.. as I recall the cruise control worked but might have sort of surged a bit.

It worked for a year or so and it went into some error and I removed all of it, fun experiment, not very practical.

I dont like them because I like to drive based upon where other cars are on the road so I have room open, on a long drive it might be nice to be able to move my gas pedal foot around a bit. Mine has it but it was unplugged on the passenger side inner fender area, as mentioned above. I could see trying to get it to work just because it was an original option.

I read an instance of this lady on the freeway near here that fell asleep driving in her new car, the guy driving beside her noted she was asleep at the wheel (literally) so he called the cops. the cops pulled her over somehow, maybe they just stopped in front of her? She was fast asleep.
