LS factory cruise control hook up

You can use the Grey wire to trigger the Cruise light in the DD gauges. The light requires a ground to trigger it, so you will have to connect the grey wire to a relay in order to accomplish this. So when you turn the cruise to "on", the DD light will come on.

a UPDATE!
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

Thanks to the volumes of information in this thread, I'm almost there to cruise control! Wiring is done and checks out. I have an s10 steering column that doesn't send power to the C terminal when the RA button is pushed....so I ordered a new cruise control switch. I believe when I have this fixed I still won't have working cruise because I have LED taillights.

LS1NOVA71 has said that putting an 1157 bulb off the brake switch should give the resistance I need to overcome this. My question is, what does it take for a resistor to do this same thing. Common 6ohm 50 watt resistors they sell for LED's advertise as getting very hot. I'd rather not have something under the dash that gets hot like this but will if that's my best option. Are there other options? Thanks!

I have found out that resistors do tend to get hot which is why I never use them. You can also use a micro relay, using only the coil part which will also work, and being a relay they are made to be on for extended amounts of time without getting hot.

Thanks! I like that idea a lot better. I'll do that this weekend and report back.

have not read entire post has this been done with a 6l80e

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?

They will work, but you will have to wire in relays to switch the normally closed switches in them to normally open.

Nice work... First think after my swap... Cruise control

[y5mgisi]

I have an idea for everyone (like me) who would like to run this cruise module but either doesn't have an ls or isn't running a vss. I think you can use a DRAC module (also known as a vehicle speed buffer) to run any of the in line vss senders like the jags that run units. The drac module is found on most all 90-95 or so gm vehicles. They don't seem to ever have any trouble and are probably only a couple bucks at any junk yard. They put out the required 4kppm signal (originally sent from the drac to the speedo) that this cruise unit requires.

The secondary benefit from this drac module that I can see is if you wanted to do it differently, it would allow you to run a normal electronic gm vss at the Trans, up to the computer and drac, and run a normal gm electronic speedo head unit in place of your old cable drive unit. So, just thought I would throw that out there.

I'm using an ls1 out of a 2002 ss camaro for my swap. What year cruise module should I be looking for? I have the one from the 02 but see now it's a good module to use. Do the cruise cables work or do the need to be modified at the tb end?

You won't have to modify the end of the cable if you're using a Camaro cruise module and putting it on a Camaro LS1.

[UATahoe]

But I need to use a module from a 98 camaro right? The 02 one I have will require the h pin to be connected?

[ls1nova71]

If you have a 2002 engine, and a 2002 cruise module, just wire it up like the factory did. the H wire is the cruise inhibit and just goes back to the PCM.

[UATahoe]

Oh ok. Gotcha. I thought there was more to wiring it up through the ecu. That makes it stupid easy then. Lol. Thanks nova!

[UATahoe]

Where does the h wire go to on the pcm? What signal is the h pin?

[UATahoe]

Figured out the pin locations. Anybody have any idea on where I can find the wiring layout of the factory cruise? I have looked through the wiring manual but couldn't really find what I was looking for. Was thinking there was a color layout on which wires performed which functions within the column. My turn signal lever also has the windshield wiper functions built in to the stalk.

[ls1nova71]

Where the cruise switch plugs in there are 4 wires, they are as follows

Pink- ignition power
Dk green - resume/accel
Dk blue - set/coast
Gray - on/off

Thanks nova! Saw the color layout in the first post but wasn't sure if the switches with built in wiper control had different color wires. Thanks again for all of the info!

hey LS1Nova I have a 2005 5.3 in my truck but im running a 2002 PCM and cable throttle body.

I have to find a cruise module and pigtail still.
(side question: can I run one from an s10 as long as it doesn't have a wire from the H terminal and just go to the dealer to get the correct fitting for it to mount on my throttle body?)

ideally id like to run a toggle to power the system and a momentary to set it just to keep a cleaner look.

so for the toggle switch it would just be:
the grey wire which should be on/off (terminal A on the cruise module) on one side
the lead to 12v with the ignition on the other side?

for the momentary switch it should be:
one side going to the dark blue wire which is set/coast (terminal B on the cruise module) the other side going to green which is resume/accel (terminal C on the cruise module)
in the middle would be the 12v with ignition on


other than that I just follow everything else you posted in the original post?

You can't really change the end of the cable very easily.

one side going to the dark blue wire which is set/coast (terminal B on the cruise module) the other side going to green which is resume/accel (terminal C on the cruise module)
in the middle would be the 12v with ignition on This is correct if you have a two position toggle switch, you just have to make sure it rests at no voltage.


other than that I just follow everything else you posted in the original post?Correct

Answers in bold above. As for the H terminal, if you get a module out of a truck, it will be fine, the not having the H is more for car modules.

perfect i found a silverado module that ill be picking up along with this brake light switch i found on amazon

Amazon.com: ACDelco D862C Professional Brake...
i do have another question though... how exactly do you hook up a momentary toggle switch like this with 6 leads on the back of the switch????

Amazon.com: 1 Piece Blue (On)-off-(on) On-off-on...

[ls1nova71]

Not sure how to hook up that switch, but would assume you would only use three of the terminals. The switch may have a diagram on it, if not you would have to just check it with a multimeter.

[68c10airstream]

I'll go out on a limb on your momentary switch. If the switch returns to the center and you can toggle it up and down this is my wiring layout;

Ls1 nova's plug in wiring layout applied to your momentary switch would be
Power from fused source (pink) to the center terminal

resume/accel (dark green) go to the next terminal say it's the above terminal in the above illustration

set/coast (dark blue) goes to the lower terminal, say its the terminal below

The key here is the wiring needs to be all in a row, as an example take all the rh terminals on the switch shown, center is power in, upper terminal makes contact with the center terminal when the toggle lever is pushed down, lower terminal makes contact with the center terminal when the toggle lever is moved up..

To sum up the above description power comes into the center terminal and goes nowhere until the lever is moved up or down. When the lever is moved power then comes from the center terminal and goes out to the corresponding terminal as a momentary power signal. Hope this helps.
