The T.F.I tester. The tester consists of another module that piggybacks the original one.

To build one you need:

New Ford TFI Module ………………….obtain from Ford

TFI module connector Local Salvage yard

14 gauge wire……………………………Parts Store

3 Spade Connectors……………………..Parts Store

2 ½ inch x 5 inch Alum. Plate ¼ inch thick.

For the price of a Towing Charge you can build a tester and get on your way just by unplugging the original TFI connector and plugging it into the test module and then plugging the Tester connector into the original module. I carry one with me at all times and have helped many other Ford owners (not just Mustangs) off of the highway or home. Remember to get it back from them though !!!!

To build a Module tester see the wiring schematic. You can either crimp the spade terminals on the wires or solder them on. You must also mount a heat sink (Alum. Plate) to the module or it will burn out in a hurry. Use the mounting holes as a template to drill into the alum. plate and attach it to the heat sink side of the module with screws you have lying around in your toolbox. Also note that you must use the dielectric compound supplied with the Module before attaching the heat sink.

That’s all there is to it.
