This is the EFI electronics page.

This page contains a schematic for turning a good TFI module into a diognostic tool. This is done by attaching an old TFI harness plug (the new part number is E5ZZ-12A209-A) to the three distributer pins so that when the TFI tool is plugged in series with the vehicles TFI and plug, the vehicle will start off of the TFI tool, even if the vehicle TFI is bad. This is usefull to diognose the TFI without trying a good one on it, and if you break down along a highway.

E-mail me with problems or concerns over your Ford electronics, trouble codes, etc, and I will respond as to where I would suggest to look for the problem.
