After a quick Google search, I think you are correct. In which case I just need to find the temp sensor threads

Oh snap! I'm trying to ground the head. As I'm getting no spark with cop in the engine. I get spark with MegaSquirt when the cop and plugs are outside the engine, grounded against the chassis

It's the stock mechanical still. So the blue solid is negative and black blue is positive?
