LS factory cruise control hook up

[nsocwx]

I followed post #1 about a year ago to create a harness for a LS cruise control in my 72. I didn't want to replace the brake switch for a LS style one so I came up with a solution to use a relay and 10k ohm resistor to emulate the behavior and make the cruise module think I was using the correct gear. The brake relay is normally open sending power to the clutch input and also provides the brake a source to ground via the 10k resistor. When the brake pedal is pushed it kills the clutch signal and sends 12v to the brake input. Viola!

Jump forward to now I finally got myself a Rostra cruise control switch and when I was probing the function I realized that the set button is normally closed which does not work for the LS cruise.. doh! Another relay to the rescue to just swap the way in which the signal works. There is probably a better way to do it, but this works just fine for me in practical application. The 'set' relay is energized when the cruise is switched on and clicks off briefly when you hit set.

Since I had to relook at this I cleaned up my schematic and I'll post that here in case in helps anyone. It's a little odd, but it works for me. The diagram shows 12v coming from the battery directly for simplicity, you would want to use a switched source as I have done.

Reviving an old thread to help a buddy. 2002 6.0L cable drive, 4L60E, factory cruise control module (pins A-K). He has a Dakota Digital HND-2 box to control it. Does anyone have a schematic for that configuration? I've found several for that configuration with a DBW, but no cable drive. Thanks!

have you googled?
i did... "2002 silverado cruise control diagram" and lots of diagrams pop up..

I had a 2000 style cable driven throttle body, matching cable driven cruise control module, and factory 1987 cruise control switch, wired it exactly like the OEM diagram, worked exactly as OEM. nothing special, follow the wiring diagram.

Just about ready to start wiring the CC module for my '67 LS1 swap.
My cruise stalk/switch (from some year of a factory vehicle?) has red, green, yellow, and blue wires.
So far I haven't found that combination in any diagrams.
Anyone have any info for it as far as which color wires are for which function or how to determine?

post a picture of the switch, maybe I can find a diagram to help

You Got lucky finding that switch, they're hard to come by these days. That is from a 1981 van or 81-83 truck.
Blue- Ignition 12v
Red- Set/Coast
Yellow- Resume/Accel
Green- On/Off

A million thanks....I've looked everywhere but wasn't sure what it came from....
another piece to the puzzle....

one last question, will this switch need relays or will it wire directly to the CC module?

No relays needed with that switch since it's a GM switch

Ls1nova71 do you have any of your switches available

Confirming payment for a switch and the correct delivery address.

Being based in the UK, getting PayPal to use American Zip Codes causes all sorts of issues when trying to use my American family as the shipping address and my UK address as the billing...

Appreciate you checking in though, pretty sure I will have some questions when it becomes time to hook it all up....

Does anyone know if a 2002 dbw tac module or stock ecm has a cruise engagement signal. I have Dakota digital dash and was wanting to use the custom inputs to show cc on the dash. I’m thinking I could use the positive input available to show cruise on by tapping into the gray pin 14 wire telling the dash that the cruise is turned on. But is there a way to tell the dash that the cruise is engaged?
