I just got my shift light and to hook it up, the directions say to hook up one wire to ground (ok easy) one wire to 12v (also easy) and the third to either the tach signal wire or "the switched side of the ignition coil.
I assume the "switched side" of the coil is one of the wires going into it, but there are two...so which one do you think I hook it to?
OR
could you tell me where the tach signal wire is...
(on knees) plllllllllllease help.., need it for racing this weekend!!
