Wiring OER tic toc tac with Evans harness

[Bleep Bleep]

Car originally came with only the clock. The OER ttt unit is installed. I have the harness from Bill but really unsure now of proper connection points? Are all or only some of the harness connections used?

Is there a Mopar Wiring for Dummies manual? Appreciate any direction guys!

It would help to know which model and year Simca you are working on. The tach feed from the coil is a separate wire not made with any harnesses.

Yea sorry. 70 Charger RT 440 4 spd.

Like I said above the coil feed to the tachometer is a separate wire not in the main harness along with the rest of the needed wiring. . Tach harness

To be clear, you’re saying for my make model the Evans harness doesn’t have a needed wire to the coil, and the Mega Parts harness is what I need instead? Correct?

The original Chargers all had the tach wiring in the harness. They all had tachs. After that I guess they watered them down to optional tach? Interesting

Maybe. Let’s clarify my question with @pnora first.

It sounds plausible with the 70, they came out with the XH cars.
