I am installing a roll tach in my car and have already bought a new wiring harness for the guage cluster, I would like to know how to wire in the roll tach. On the back of the tach it has coil and 12 volt inscribed. There are 2 prongs sticking out on the back side of the tach. Just guessing it looks like 1 lead would go to the - side of the coil and the other side to a 12 volt acc. Any help would be greatly appreciated.
Thanks In Advance,
Joe

Pink wire, 12v from fusebox with key on, goes to 12 v prong on tach.
Tan wire from coil - goes from coil through the bulkhead connector to the coil prong on tach.
If you purchased a new dash harness for gauges, the connector plugs should fit the gauges properly.
