This came out of the back of the original 4 rotary compressor. Can't seem to find one like it in any condition. All new or rebuilt R4 compressors come without the switch. Instead, there is an aluminum plug you replace with a new switch at time of installation. I don't want to use the old one. There is a similar R6 compressor super heat switch I see online but it looks different, there is a post on those I don't see on the one out of my car. There's some air conditioning parts specialist with this out there somewhere.

 

I am afraid this is the way you need to go. I wish you posted this 2 weeks ago. I just replaced the compressor and accumulator on my dad's s-10 and threw out the plug on the compressor which I believe is the same diameter. MT0674 on page 10 or AP air 220-420

Much appreciated. Is see the upgraded switch with a wire connector. Unfortunately I will need to change the plug on my harness but she is no trailer queen, this will work great.

 

I ended up finding a superheat switch I needed on ebay.

 

Thanks for the information, I appreciate the reply.
