In this video I go over reading the voltage of the signal wire from the ignition to the ECU. I also included a few clips of how to wire in a 12v to 9v converter in order to fix a no voltage problem or a 12v reading on the signal wire. I also included a diagram of how to test this signal with a 9v battery.

If you do not feel comfortable with electrical or wiring, please find someone qualified. The diagrams were quick and dirty, so please use caution. Read out your own voltages and make sure you are using the proper pins for your connector. I tried to be as detailed as I could but I'm sure I've missed some details so feel free to ask.

the best way to contact me in regards to these questions would be on this thread.
