Does any one know if on the high side compressor cut off switch if color matters. I see them in blue, green and beige. Rockauto mentions the color so I am wondering if there is a difference. Mine is two wirer green.

If anyone knows is there is a pressure relief valve that should be changed on the compressor. Its a Harrison 328 if that matters.

With the price of refrigerant I would like to get it all correct before I start dumping it in.

Thanks.
