Default 1998 xj Accumulator sensor/plug

I was wondering where I could find the plug that the electrical connection connects to on top of the acc. Also that electrical connection that plugs into it doesn't always have power when I put my light tester to it. Where does that wire come from if I need to trace it back?

The electrical sensor on the accumulator is the low pressure cutout switch. It's wired in series with the high pressure switch on the manifold lines near the compressor.

In order for the low pressure switch to recieve power your ac must be cut on. Use the schematic about to help.

I stuck a needle through the wires and my light tester didn't light up. I had power through the cone to open last night at times. So it looks like my electrical problem is intermittent as if I have a loose connection prior to the ACC connection. I'm unable to clearly see where the wire runs from due to being on my phone. Do you know where ties in to?

The high and low pressure switches are ground switches. Jump the two wires together to complete the circuit.

I decided to take out the a/c heater control and stick a needle through the light green wire and I had no power. I pretty darn sure that it's my control unit that's bad. I'm getting one from a local salvage yard tomorrow.
