how to jump the ac compressor

Is there a way to jump the ac compressor other than plugging 12v into the unit itself. I cant reach inside to get to the wire.

I have no idea why the compressor wont start. the red ac light stays lit now on the climatronic. coolant temp sensor is working, tried the reset/recalibrate thing with the control panel. I checked the pressure is 80-100psi on the low side depending on temperature. maybe I have a failed pressure sesnsor but i have no idea how to test that.

You are absolutely wrong! those are the pressures when the compressor is RUNNING! if you read the above post again a few times you will see this is a compressor that will not start. If I had the pressure are describing I would have a working ac.
