80-series A/C compressor/clutch wiring? (1 Viewer)

[Arizona Wilderness]

Does anyone have a photo of the plug/wires that show how the compressor and clutch connects to the wiring harness?

I had a belt break and it took out the wiring. I'm left with the wire from the harness containing 3-wires. One plugs into the compressor w/a single plug. The second is a blue wire with a forks spade clip. There is a third wire with black insulation (haven't stripped) with no plug, and no obvious place to plug into.

Thanks!

The plug mine still has is pictured here:

So basically I'm wondering where the other two wires from the harness go.

Thanks, I think you just posted this when I was posting the pic above. This is interesting. Let me go take a pic of mine because it looks like I'm missing a lot.

The above picure was copied from another thread. it shows the oil pressure/ac wiring harness connectors. 2 go to the oil pressure gauge and the other to the ac pump. Here is the link to the thread it came from - Oil Pressure Gauge FIX - https://forum.ih8mud.com/threads/oil-pressure-gauge-fix.1063285/page-4

You can still buy the harness from Toyota if you need to replace it 82221-60020. It would be the easiest fix if you have a lot of damage. One of your connectors might still be on the oil pressure sender so it might still be "fixable" if you re-pin the connectors.

Best of 9 I was able to get just now. Thanks again. FYI, green light is coming on on A/C button, but magnetic clutch is not engaging.

Wait a minute, so that means the magnetic clutch should be engaging based on that one wire being hooked up? Thanks!

The magnetic clutch is just a 12V electromagnet. One wire in is +12V, the ground is through the pump body into the engine block. You could test the magnetic clutch just by bridging the single terminal input to the magnetic clutch to +12v on your battery. I had something similar a couple of weeks ago - fan belt broke, took out some wiring on the way out, but in my case it sheared the AC clutch wiring between the plug and the magnet, right up on the snout of the pump, which is a lot harder to deal with properly. I bodged it while out and about with a gas soldering iron and hot glue. That should hold it until some future period of time when I have to do some work on the AC system and can pull it and fix it up properly.

Perfect tips, thanks!
