I’m wondering if my OER tic toc tach (69 Bee) is causing my no spark issue and curious if I have it hooked up correctly. The gray tach wire is going to upper terminal and red wire to bottom terminal. Not sure if I labeled the back correctly, so disregard my notes on tach back. The clock works when powered so maybe it is correct.

FSM shows tach with two posts only and no mention of which is +- for the gray and blue wire to go.

To wire a Mopar Tic Toc Tac, connect the blue wire to the fuse box for power, the gray wire to the negative side of the ignition coil, and ensure the tach grounds to the dash frame. If your car didn't originally have a tach, you may need a special harness for proper installation.

Thread... how to wire tic toc tach?
 
Car originally came with Tic toc tach. Looks like I’m hooked correctly then, gray wire is to longest stud and red wire is going to fuse panel.
