Want to wire in a Tachometer
« on: July 19, 2009, 09:34:14 PM »
Found a old tach in my buddies garage and want to wire it in. Where do I get the tach signal?

I believe the white wire at the ignition control module is the tach signal wire. I'll have to check to be 100% certain though.

Yep, it's the only white wire in the larger 6 wire plug.
