Air Conditioning Relay Location??

I am in need of replacing my A/C relay but dont know which one it is. I have a '90 4.0 and the relay center under the hood has 4 in a row, but dunno which is for the air.

TIA

I'm pretty sure it's the forward one; however, someone had shuffled them around on one my XJs. The other three are fuel pump relay, B+ latch relay, and o2 heater. They are all the same part if you want to swap them around.

What year?

On my '98 is located in the PDC and the relays are labeled under the lid covering the fuse/relays. Mine has stuck 'on' several times which is why i added bypass switches to limit the constant cycling when not necessary.
