Doing some research on "possibly" adding rear AC. Yes I know it would be a B*** to do. I can find the wiring harness for the blower unit itself but not the one where it would run from the fuse box to power the unit itself. Or for that matter if its installed on all trucks or only those that came with the rear AC. I dug around on rave but no luck.

Thanks

 

Not sure what you mean by "to power the unit itself." As far as I know, the blower unit is the sum total of the rear AC components other than the coolant lines, the ducting, and the overhead switch. From a wiring point of view you probably only need to identify the harness that goes to the overhead panel, behind your headliner, if you've already found the power supply for the blower unit.

 

I have found all the parts besides the harness that would supply 12 volt power to the motor and conden unit itself. The harness for the switch is simple and there are many on ebay. The part that I am trying to ID I think would come somewhere from the front of the car.

 

Why do you think that there's a piece aside from the ones you have identified?
