I am needing a wiring diagram ( with pictures ) for the vehicle listed above 4 x 4, 3.0L automatic. so I can determine where to put a plug in that's loose.
This plug in has 2 wires on it and it looks like it might be the high pressure connection, the location of this loose wire connector is on the passengers side of the truck near the front .

I attached the wiring diagram for the A/C system. If this is on the right side of the engine, I suspect it is for the A/C clutch cycling switch. Let me know if you need more help figuring this out and we can go from there. Thanks

The loose plug in is on the drivers side up near the radiator, it's not the low pressure switch or the magnetic coil plug in.
The plug in will reach near the radiator on the drivers side.

Okay. In the first post you said it was on the passenger side. If it is on the drivers side front, it appears that would be the high pressure switch. The switch itself is on the A/C line so you should be able to find it.

It appears that is the only 2 wire connector on the A/C in the front driver side of the truck. Maybe get a picture of it if this isn't it.

This is on a friends truck, I looked for that pressure fitting on the high side line, it doesn't have one unless someone changed that high side line. What do you think ? Can I use a jumper wire on this high side line for a minute or so to see if the compressor clutch kicks in, I think I should be able to. without any damage, let me know.

Yep. It is a simple switch that just needs the contact closed so you should be able to jump it to test to see if that is why the compressor is not coming on.

okay, can you find a picture of the high pressure line that has the switch connection on it? because we cannot find one on this high pressure line that's on the truck right now. I'm not sure if this line has been replaced with one that doesn't have the switch on it for the plug in to go on. Thanks

Check the compressor and see if it has the high pressure switch on the line coming out of it. Take a look at the diagram. I think the 3.0L and 4.0L are the same.
