Hey guys, I need some serious helps with re wiring my air conditioning. Just don't even know where to start. I guess I should probably start with why I need to re-wire it, the reason is because I put a PowerFC for a JZA80 supra, and remember hearing that the signal for the magnetic clutch on the supra is the opposite than for the aristo.

So far I'm pretty sure that wire just triggers a relay in the main fuse block, but will it be as simple as re pinning the relay to make it work with the powerfc, or will it be more complicated.

Hopefully someone has some more information on this. I've tried searching around a bit but can't seem to find the information I had found once upon a time haha.

If you need to swap from a positive trigger to a negative then just install a new relay...and use the trigger coming from the PFC to trigger the relay and the relay to trigger the A/C.

Pretty simple IF that's all you need to do.

should be as simple as if you need to use a positive triger and it had neg triger just cut the wire from relay oppsitte to the triger (which is the one that comes from the ecu) which should have be conected to positive and connect the relay end to ground and you are done
