I am trying to clean up the wiring on my 350. I am replacing spliced wires that change colors once or twice along the way and go to places not as shown on the wiring diagram. I am also replacing a few missing wires. The thermal limiter was missing so I have added that back in. That leads to the problem.The black wire from the limiter goes to something called Compressor Super Heat Switch. It appears to be a relay that goes to ground. Where is this thing located? The diagram only shows one wire going to it. Thanks for the help. Lou
