I need to short out the terminals to turn the A/C compressor on.

 

I was just about to post the same question. Anyone know?

 

I found reference in A/C posts to jumpering a red and grey wire, and then noted that the electrical connection going to the high pressure side contained wires of this color.

However, I didn't dare jumper something without confirmation and I don't suggest that you do either!

What I can tell you is that if you have a guage hooked up to the low pressure line, and the compressor is off, your gauge will show a TON more pressure.

My example was that while the compressor was on I was reading about 35 psi, but when it was off I read about 220 psi. I know this doesn't help if your readings aren't normal to start with, sorry!

 

Should be the red/black and grey wires are the two that you jumper on the connector. The sensor is on the a/c pipe right at the RH shock tower.
