This is where I was told to put my water temp sender, but it is metric. Everyone said that it was 12mm, but nobody ever said the thread pitch (that I could find anyway), so I bought M12x1, but it was a bad guess. What you need is a M12x1.5 to 1/8"NPT adapter. This is Auto Meter part# ATM-2277. Hopefully all of these specifics will help someone else to not make the same mistakes I have.
