Okay guys. I bought the autometer adapter that changes the stock 12mm head threads to 1/8". The problem now is I cant find a temp switch that is 1/8". I would rather not drill and tap the head for a different size. What are my options here?

Autometer short sweep gauges use the 1/8NPT sender...

I need to fit a temp switch to one of the heads. I don't have the switch yet. They dont seem to make any that thread into the stock head location. Most i find in the right temp rang are all 3/8" npt.

They do make one that fits in head, Dakota Digital and Classic Instruments have them. Ive used them both. Steer and Performance also makes the adapter for a122M to most any aftermarket sender.

The only temp switch I have found in M12x1.5 is a Wells SW 1902

Painless makes one, but you have to buy an entire kit including fan control relays.
