I have a 2001 Super Duty V-10.

Ihave bought an after market tach and cannot figure out where the green wire goes.I know someone outthere knows. Please help

 

If it is the tach wire you are looking for on my 2001 E350 it is a white wire with a pink tracer hanging out of the main wire harness just to the right of the brake booster. It has a white tag on it labeled CTO. Hope this helps.

 

Find your Coil and hook it to the Negative wire.

 

He has 10 coils, thats not going to work.
