Hi Cody, One of the parts I was actually able to get was the receiver/dryer assy with the new pressure switch. For initital testing, I jumped (shorted) that switch to get the pushbutton for AC to work.
What I can't figure out is what the ECU is doing electrically to allow pin 106 to become the ground for the AC relay. The only way I've gotten the AC relay to work is by manually grounding the wire going to pin 106. If all else fails, I could rig a relay in the car to accomplish that outside of the ECU, but would lose idle-up, and accell cutout.
(Note) Coutesy also sent the wrong HP line from the comp to the cond and since I opened the plastic wrapper to discover this, I can't return that $85 piece. Looks like custom made lines are the only way to go if you want them new.

That might have made this all more simple Irving. I worry about putting these lines back together, then getting it tested, and having to disassemble the front end of the car at the AC shop. We're replacing 100% of the components under the hood. No way do I want the AC shop removing the front bumper, lights, and intercooler to get to the fittings on the condensor.
Maybe I am overthinking this, nothing will leak, and everything will work when filled with freon. lol..
