2000 Cavalier cruise wiring Sign In

Does anybody have a wiring diagram for a 2000 cavalier. I need to know where the 10 wires on the cruise control module go to. I also need to know where the controls on the turn signal lever go, and where the brake switch wire in. I am putting factory cruise on a car that didn't come with it originally. Please send me anything you can find. Thanks

Here’s a diagram for you, all I ask for is an up-date on how the job went.
The only concern that I would have is whether the PCM in your car will allow cruse being that the car never had it. You may end up having to have the PCM reprogrammed to acknowledge that there is going to be a cruise control request.
That would mean finding another Cavalier that is identical to yours that has cruise and use its serial number for the programming. The dealer may have a program that they can down load if needed.
Just a thought.

Thanks.
I am going to call the dealer and see if the crusie has to be programmed into the PCM. I will definately let you know how it goes. I am sure I will have some other wiring requests in the future. GM should make this wiring info public so it isn't so hard to find. I know it costs to subscribe to a service to get this info, and I appreciate people like you that share this info for no charge.
This board is great! I will definately bookmark this one.

I got the cruise installed this weekend. Everything went great. With the schematic, it was easy to get the wiring off of the junk vehicle. I didn't have to trace the wires, just look at the schematic and cut them. I checked the cruise inhibit wire to make sure the PCM grounded it when I was going over 25mph. This is what enables the cruise. That worked so I knew the cruise should.
Also, the wires for the PCM were already run up to a connector by the firewall. I just took the pins out of the junk car and plugged them into the connector. I also did that with the wires for the fuse in the fuse panel. Then there were 2 brake switch wires to connect. The correct switch was already there. Also had to find a ground, a nice stud by the transmission. That was it.
Only took a couple of hours, and most of that was trying to get the module to miss the A/C line. I had to modify the stock bracket a little. The donor car was a 2004 with a different engine. They must have changed things a little.

Thanks again for the wiring info. It would have been almost impossible without it.
