I bought a used tach and am in the process of cleaning it up for installation. The back two wires were unattached, and I don't know which wire goes where. Can someone identify these and tell me which goes on which side (red and red with white stripe), or if it even matters? Thanks.
It will be on the right side of the steering column, close to the firewall, and will be a heavy gauge red wire that is plugged together with a black connector. Unplug that connector, and have the tach in series, so red wire coming from the ignition switch, to tach, then tach to the firewall side red wire connector. May have to try swapping the wires on the tach around if you loose voltage to the distributer.
