Help with tach hookup on 67 coupe.
 

I have a 67 coupe that has been converted to EFI. There is a connection that the direstions say is to hook up to the 'S' lead from the tach. I pulled that dash apart but have not been able to find this wire. Has anyone done a conversion like this? If so, what wire do I hook up to? Does anyone have a copy of the wirig diagram for a 67 GTA?

Thanks,

If your 67 didn't have a factory tach in it then it will not have the tach wire in the wiring loom.

It does have a factory tach. I cannot find a wiring diagram that has the tah connections in it. Do you know where I can download one for a 1967 coupe from?

I just looked again in the Classic Mustang tech site and it didn't show the tach wires, but I looked in my Haynes book and it did knd of show it. It showed your tach wires as being Red-Green stripes. Does the S mean switch? If you have a Haynes book it's on page 10 for 67 mustang wiring.
