Tach Help,

Hi, I just bought a Autometer Pro-Comp tach at a swap meet and im trying to firgure out to install it. The wires are not like on a regular tach where there is a red, black, green, and white. This tach only has two black wires coming out of the back. If anyone can help me or point me in the right direction I would appreciate it. Thanks,Mike

Heres a few pics of mine. It says pro comp 5710 on the clamp.

I've never used a Pro-Comp tach , but I'd say your answer lies in picture number 4. "Warantee is void if used without 605 sender". Looks like you are missing a sending unit.

All you have is the head, you need the sending unit.

Thanks for the info, Does anyone know where I can get the sending unit, I was lookin thru summit with no luck.
