Cruise Control

[Urbanburban22]

Hey GTP51, were you able to resolve this?

Hi David, I haven’t sorted it yet, one of the other toys needed some attention. As it turns out another involved under dash job, I’m just to big and too old for under dash stuff now…lol I won’t get back to the truck for a few weeks, but if I manage to sort it I will let you know
cheers

I have a new turnkey 350 that I pulled the Edelbrock carb off and installed the Sniper EFI. This 1979 Sierra Classic has the cruise button in the end of the turn signal stem. There is a chip of sorts in the glove box box with a label on the envelope that says "cruise control." I contacted Holley and they said they have a kit. Has anybody been here?

From what I can figure out is it was to power on ecu and signal wire back to obd port.

Hi guys apologies for the delay getting back, in the end I gave up and removed all the vac and mechanical cruise control components in the engine bay, I will look for an alternate solution at some stage . It’s just too hard playing under the dash of these old trucks, I’m too big too old and too grumpy to play that stupid game now, thanks to everyone who chimed in on this one. I usually just persevere until I find a solution but this one was a bridge too far.

Rostra makes a very nice aftermarket cruise control setup. You can use the factory cruise lever to control it.

On my 81 GMC, I used the factory speed sensor. On my 69 ok, I had to use the Rostra speed sensor that goes inline with the speedo cable.

Both systems work very well

This. All their stuff is top notch.

If you have a carb or throttle body you may be able to use one of the cruise modules off a TBI truck from the early 90's. They are usually mounted on the firewall and have a cable to the the throttle units but I think it will require some kind of digital input from a speed sensor. I could be mistaken though and maybe it also needs a PCM input. I've looked at having it setup on my LS swap and I know it works there, but just haven't gotten far enough to know more about setting up the cruise.

Use the module from a 96-2000 GMT-400. It is completely stand alone. I have a harness diagram and also a diagram for converting the Rostra turn signal stalk for a 80 and earlier year square to feed the proper signals to it. You need a few relays to convert the signals from the stalk to what is needed for set/resume/cancel into the module.

Do you have the diagram still to convert the CC stalk with relays?

Yeah, it's in my shop somewhere... I'll try and post it up here tonight when I get home... If I remember
