Default 2001 Tracker AC

So I'm looking at my neighbors AC on their Tracker.

Does anybody know what they use for a cycle switch on these? There is no accumulator or cycle switch that I can find. I see the high side fan switch(s). I thought it was an Evap temp switch, but I can't find one on the evap (or I can't see or feel it). There is a switch somewhere keeping the clutch from engaging.

Or, does anybody have a wiring schematic for this thing?

I think I found the relay. It's energized, but I don't have my 12 volts going to it for the compressor clutch, and I can't find a fuse that feeds it either.

it doesnt have a cycle sw, the DEF fuse 15a powers the compressor relay and the 60a HTR fuse powers the A/C 25a fuse and that is what powers the clutch, i have a diagram but not sure how to get it to you.

Yeah, I'm pretty savvy with AC stuff. I have power to the relay coil, just not on the common side of the relay to power the clutch.

I put a jumper on teh battery to the clutch and the AC runs awesome, not low at all. Just need to figure out why I don't have 12v on that one side of the relay.

Found that fuse! Thanks! The fuse was kind of sitting all by itself, next to a bunch of relays under the hood. I thought it would have been in one of the two Fuse Boxes on that vehicle. But, it's working great, thanks.
