I thought my timing light was broken until I tried it on my other supra. The tach in the car stopped working the exact same time the CEL stopped working. It looks like I have finally got all the wires on the harness right but no tach signal or cel signal. Any ideas?

Yes, either your pick up, the wiring, or the tach does not work. Start at the pick up with a DSO if you are going to try and figure it out yourself.
