Ok my tach is not working. I've already tried swapping out the distributor with my other ARR. So it's not the dizzy. What else could it be? What other sensor monitor engine speed? I'm sure the rpm signal is getting to the ECU cause i could still hit the rev limiter. I'm not getting a CEL. Still runs fine.

For right now I just spliced the blue wire on the dizzy straight to the blue wire near the clutch resevior. It works but I don't like the extra wire going through the engine.

Thanks!!
