My dad has a factory tach and harness he rounded up years ago. Thing is the harness that came with it is out of a manual transmission. (No gear lamp or reverse lamp switch) Can that harness be modified to work on an automatic car? Most of the wires in the tach connector are similar but I'm wondering if the whole console harness is different as well? This is a correct 4 wire tach as well.
To further describe the harness we have there is a piece that plugs in at the kick panel and runs to the center console. There is then another short piece that plugs into that and has the console lamps,gear and reverse lamp wiring.
Also is there a way to test a 4 wire tach before going through all this in the first place? Seen where you can do the battery trick on a 3 wire tach.
