I need some guidance. Here is a little background. My 2007 EX V6 wiring was damaged by squirrels. I purchased a new engine wiring harness and installed it. Everything works correctly but the A/C. When I turn on the A/C everything seems fine except the clutch does not engage, so no cold air. If I apply 12 volts to the compressor, clutch engages and it blows cold air. Here is a list of my troubleshooting so far:
1. Checked all fuses market A/C.
2. Replaced relay.
3. Jumped pin 1 and 2 of relay - Clutch engages and blows cold air.
4. Tested A/C pressure switch. (4 wire) Pins 1 and 2 have continuity, pin 3 and 4 are open.
5. Checked pressure on High and Low side everything good.
6. Turn on car, push A/C button. Car idles up and condenser fan turns on. (still no clutch).
Any other suggestions?

 

is there continuity from the relay to the comressor clutch terminal?
