I got all the wires ran correctly on the car except the gray tach wire, i wired it to the freen and yellow striped wire and i lose all spark, but when removed car sparks, what color wire is the correct one?
I may be wrong about this because its been awhile since I wired one of these. But, I'm pretty sure that if you use the TFI wiring harness you do not need to use the tach output wire.

Right on target for use with the stock tach.!
The TFI module dark green/yellow wire feeds the stock tach and the computer. Make sure it is connected just like the stock setup.
Only aftermarket tachs use the MSD tach connection.
