Does anyone have a part number for any GM temp switch that would energize at 185°F +/- or so and de-energize at 165°F +/-? I do not want to pay Painless or any other place over $50 for a wiring harness for my Winstar fans. They just mark it up and do what I can already do! List a part number. I would consider any make as long as it did what I wanted.
