Ive looked prty close on my 15 and can cant find a damn thermister anywhere (not saying it doesnt exist, just i havent found one). On my 11 model truck i unplugged the thermisters and power the compressor off a toggle switch. The problem? I have no freeze protection or over pressure protection. The existing high psi sensor and computer cycles the fan fine with the thermisters unplugged. But without a low psi switch it will freeze up and without a high psi cutout it can blow off refrigerant and send ur 300$ compressor to the scrap pile.

that compressor can fairly easily be controlled with an arduino. Here is one method...
