Thanks for any input.Herb
The operate full-time on 14V, you will need to bypass the resistance wire under the dash. You don't even need to cut it, just Scotchlock a connecting wire at the tach end of the pink wire, and at the firewall. If operation of the car is changing, though, something else may be happening.
