Sounds like a neat installation also. I'm using a Camaro harness so it's a little different. I figure I'll tie the yellow and black wire into the Camaro VSS back to the ABS. Then I'll tie the purple wire back to the Data link connector and the other purple to the brake switch and the ABS is complete. As far as the Cruise control wire LT BLue w/ black stripe goes, It'll go straight from the PCM to the Cruise control module. How did you make the inlet air actuator for the A/C work? The old PCM did it and there's not a place for it in the new PCM. Did you just aplly power to it and let it recirculate in the cab all the time?

I&#39;d have to look at the details to be sure on the ABS wiring, but all the colors from the new harness matched to what was on the truck. The yellow & black VSS wire I believe goes to the actual VSS sensor. I believe purprle and/or purple & white went to the firewall and to the ABS. I&#39;d have to double check my connector end views. If you are mixing and matching wire colors, then its not being hooked up right. Same thing with the cruise control, all the colors should match up and work just like they did on the old harness.

I did not hook up the air inlet actuator wire to anything. It&#39;s just taped off and tucked off to the side. The A/C recirculation works just like it should, if I turn the A/C to max, it comes on, or if I hit the button, it comes on. I&#39;m guessing that wire was just some sort of output to the PCM for some sort of control that the new PCM does not use.

The air recirculation gets it power from the red wire with a single 1 pin connector on it that goes through the firewall. The 1 pin connector for the red wire is right by the other connector under the glove box that runs out through the firewall.
