Spyder tach wiring question
Posted by: Grandpacorvair ()
Date: August 16, 2021 08:34AM

Need to find out which pin, from the back, is 12 volts
and the coil wire. Found a couple of posts here but they seem to
counterdict each other.

Thanks.

Not sure I understand the question but I do know the tach wire goes on the negative side of the coil along with the points wire.

Sorry if I wasn't clear. On the back of the tach there are two spade connectors. Unmarked. One is for the switched 12vdc source, the other is for the wire (usually brown?) that goes back to the coil. I need to know the proper orientation for the two wires...

Thanks

The / above the yellow is *12V from ignition

The \ is the signal from the coil - terminal

Here’s what a more clearly marked ‘63 Spyder tach looks like, just confirming above
