tach
I am trying to install a tachometer to a 454 and the coil is made funny.There is two plugs on the coil.A red wire and white wire on each.Can someone please tell me which wire to use.

In the old days, the tach's "trigger wire" (often green) went to the negative side of the coil so I would guess it might be the white wire in your case.
