Installing Factory Cruise

And the Dealer said it couldn't be done! heh heh

I bought my '04 Cavalier in November of '04. It was a leftover stripped down model. I told them that I wanted cruise and they said that they would add it on. About a week later, they had me drop off the car and they took it to a 3rd party install shop to have the cruise installed. To make a long story short, it was a cobbled mess and I had them remove it. When my wife asked about just getting the parts to install factory cruise, she was told "You can't do that on a Cavalier with a manual transmission."  Whatever . . . . . .  Sounded like a challenge to me.


I started watching on eBay every day for cruise parts for an '03 - '05 J-Body. It was fairly common to find the turn signal / cruise switch, but not much else. Finally I hooked up with JLenko. He was able to hook me up with all of the cruise parts off of a wrecked '03 Sunfire. He sent me the cruise unit, turn signal / cruise switch, wiring harness for the cruise, and the switches for the brake pedal and clutch pedal. He also supplied me with the two following wiring schematics.

The install was pretty straightforward. I replaced the turn signal arm with the one containing the cruise switch. There were just a couple of screws to remove from the cover that goes around the steering column. Then you can see the switch unit . There are two screws holding on the switch, and then you can unplug the wiring harness.  When you install the switch that has the cruise switch , you'll have to plug in the cruise wiring harness to the back of the switch also.

 The next thing I did was install the cruise module under the hood. The bracket bolts onto one of the strut mount bolts, and another bolt that's at the top of the engine mount. Then you plug the cruise wiring harness into the cruise module. I ran the cruise wiring harness. along the top of the firewall, next to the rest of the wiring.

The throttle cable from the cruise clips into place on the throttle body. There's already a place for it to snap on.

There is a cruise control release switch that needs to mounted in the bracket next to the brake light switch. This is in front of your brake pedal. If you have a manual transmission, there will be a similar switch to mount to the bracket in front of the clutch pedal. These are obviously there to turn the cruise off when you apply the brake or disengage the clutch. The harness will have connectors that plug into these switches.

Basically all the wires are easy access, there's a big plug that sits under the clutch reservoir and has all the wires you need to tap into for the white paired with the orange wire (not the pink one). Basically picks up the brake light signal. The black w/ white tracer is ground. It's supposed to ground at the battery tray.. But any good ground should be fine.

You also need to connect to 12v power. I used the fuse box. You run two pink wires from there. One goes to the switch arm, and one goes to the cruise module.

If you've made all of your connections properly, you'll now have functional cruise that doesn't look like it was installed at a drive through auto accessory palace.

This may not work immediately, but just keep checking the schematics and make sure that everything is hooked up correctly. (After messing with mine enough, I found that I also needed twelve volts going to pink wire on the clutch cruise release switch.  You also need to adjust the release switches carefully.
