A couple of years ago I purchased a new inexpensive 5" Tach with remote shift light from a vendor at Spring Carsile.The name on the box is Performance Instrumentation type R Tachometer. Unfortunately I have misplaced the wiring diagram and a search of the Net failed to turn up anyone selling this brand. Can anyone tell me which color wire goes where? The shift light is no problem as it has a plug.
A quick search on Google showed some feedback for a Ebay seller that sold one of them. Maybe if you contacted them, they might be able to point you in a direction. https://www.google.com/search?as_q=...w.,cf.osb&fp=e46627e66b3eb118&biw=983&bih=554
