Hey well today i did the tach mod and still no tach i heard the wire for the tach comes out of the ecu and is all black
pretty sure i have the wire that goes to the tach just trying to find the one that pops out the back of the ecu

there are 4 plugs for the ecu i found 2 black wires on the 3rd small plug down that i already tested but still no tach does the wire come out of the big plug?

black tach wire should go to ecu right or one of the coils?

pics soon to come

Find the ewds for your year motor. I'm pretty sure the tach wire comes off the body harness.

the tach signal wire come from the 3.4 body harness plug and goes the the 3.0 body harness plug. The rpm signal wire comes from the ignitor and runs up the engine harness to the body harness plug where it runs to the tach.

Fixed! Ended up tracing it on back thanks for the help
