To get the AC working splice into Pin 41 on the C2 plug and tie in a small normally open pressure switch to the oil filter housing. When it sees pressure it will close and complete the ground and the computer will know the engine is running and engage the AC clutch. I had mine just grounded for a little while and for some reason it kicked the computers ass and the AC works without using this method, just posting this up for anyone that is having issues with a similar swap.
