TACH Sending Unit wiring diagram

[Glow Worm]

Hoping someone can provide me with a correct wiring diagram for the Tach Sending Unit on my 1966 Cuda, Formula S.

Also, how many "suppliers" are there who are offereing new or rebuilt sending units? Names, numbers, or web sites would be very helpful.

Check with Williamsons Instruments. They rebuild Sun Tachs and sending units and may be able to help you out. They're web site is www.williamsons.com

I am with you Glow Worm. I believe that the module in my 66 Formula S is shot too. I have 12V at gray wire only (from dist.). There is an outfit that makes replacement boards to put in the original can. They also have some info. that may help to diagnose the problem. I will post it after I find it again. Where are you located in S. Ohio? I live outside of Charleston WV and my sister lives in Meigs Co. Ohio.
