Re: LS factory cruise control hook up
Hi casaba, digging in my mental archives i believe buick or caddy used a vacuum servo mounted off to the side of the engine and used a bead chain and a pulley to make the 90 degree turn from behind and to the side of the rear of the cylinder head. I think it was in the early 70's. I think i'm getting a little older. Good luck, brian fuller

Re: LS factory cruise control hook up
Has anyone figured out how to make a cruise engaged light work?

I used a Dakota stalk and two relays (87 & 87a, 1 N. O. and 1 N. C.) and just like everyone told me it will work!!! All is good works fine, now I just need to thread it into the column and make the splices final. Thanks all for the info |

I looked into the cruise engaged light at one time, but it's kind of involved, and since I didn't have a place for the lights I never tried it. If you just want an "on" indicator, you can just tap off the on/off switch. If you want a "cruise engaged" light it takes some work. Here's a diagram I drew up that shows how to do it, but I have never tested it in the real world. However, if I remember my high school electricity class correctly, this should work. One note though, it will set the "engaged" light if the Resume button is pressed before the Set button, but of course the cruise wont be set. If you try it, post back and let me know how it does.

Re: LS factory cruise control hook up
Thanks for the diagram I will give it a try and report back. I am using a 99-2005 S-10 module with a Rostra stick and M&R closed to open circuit adaptor.
I added cruise to a GM diesel and never had an indicator light on that either. Do you know what type of signal is given to the PCM from the J terminal ? |

Heres a picture of what I did on mine . I wired it to work along side of the cruise control . It is not wired in to the pcm . The light is energized when I hit cruise . So when the cruise is set the light will come on . Also when I hit the brake it is disengaged . It has worked like clock work . If you did not know how it was wired you would never know the difference . I wired it to engage a relay when you hit cruise . I use the same power supply from the set button to energize both . It has never hiccuped .

Re: LS factory cruise control hook up
OK, so curiosity got the best of me. I took my truck and unhooked the J wire, and put another in it's place, then ran the wire into the cab and did some road testing with the multimeter. Turns out that the J (cruise engaged) wire puts out a ground when the cruise is set. So I came back to the house and rigged up a light and it works PERFECTLY! You can't make it come on until you've reached the speed that the cruise will set, then it comes on and goes off when the brakes are applied, comes back on when resume is pushed, and goes off when you have it set, but push the coast button, and when you release the coast, it comes back on. I don't see any problems with wiring it this way. Just hook one side of the light to an ignition switched power source, the other side of the light to the J terminal and you're good to go! Guess you can $h!tcan that old diagram I drew up!! :lol:

I have not tried this, but with a couple of diodes and a relay, it should work. Maybe lol!!

Re: LS factory cruise control hook up
[QUOTE=ls1nova71;6992688]What are you trying to do
I was showing a way to get a ground signal to the DD guages when you actually set the cruise, not just turning cc on/off. Most if not all of the vehicles I owned , only had the cruise icon when it was actually set not when it was turned on or off. DD makes it a little harder to do when it's just a ground signal. Like I said earlier I have not verified it, but I'm sure it will work. |
Re: LS factory cruise control hook up
Apparently no one saw post 163 where I showed how to do it with the J wire. It goes to ground when the cruise is set. Just add a power and the module operates the ground. Works perfectly.

Sorry man, not trying to step on any toes here. I did go back and read post 163, where is this j wire? I'm running DBW, if I have this, it would be a lot simpler to wire up. Thanks |

Re: LS factory cruise control hook up
Before I found this thread I hooked the J terminal up to a light hoping it was powered and of course it did not work. Now all I have to do is switch a couple of wires around and I will be good to go. Will have to wait road test a couple of months down the road.
I hadn't been on this site since 2006 and had to search for my user name by zip code and remembered the password and I was back on. Thanks |
Re: LS factory cruise control hook up
I came across these while searching for a cruise lever. Looks like they're already a 4 wire setup. Any reason why they wouldn't work?
