Re: tach does not work

check to make sure all of the wires are connected to the distributor.

Re: tach does not work

all the wiring is gone. it was cut out during the motor swap so i have to splice in under the dash.

The tach wire goes from the PRIMARY non-key side of the coil, to the firewall connector, to the dash connector, to the tach.

At the dash the tach wire is in the right hand connector, pin 7.

If the original is still there it’s a WHITE wire.
