Hi, trying ti figure out the correct wiring for an aftermarket tach. Car is a 71 Cutlass Supreme that originally had the clock gauge, but I'm replacing it with a tick tock tach by The Parts Place.
I bought a tach harness from American Autowire, but am trying to figure out the correct installation including which wires from the dash harness. Thank you for any help!
The ring terminal on the harness you bought will go to the stud labeled coil negative. The stud labeled battery needs the orange wire that originally powered the clock, the stud labeled dash lamps needs the gray wire to piwer the internal lamps
