For Project Blu (didn't oringally have AC and is a 85 truck), we got a AC switch from the wrecking yard and plug it into the factory harness. Then we had to jumper one wire behind the dash since the "AC contorl" was not there and then you just plug the AC compressor into the factory harness under the hood. your you could just wiring in a 12V+ fused toggle switch to the magnetic clutch.
As for adapting the AC Pump for barb fittings, I just weld a steel fitting to the AC Pump hose adapter plate/bracket, thus turning it into say 3/8 npt and then I just screw in barb fittings and your set to go.
