The following is part of the TFI relocation tech instructions....

Next, go to the junkyard and cut a couple of feet of TFI wiring harness and salvage the foil wrap that Ford uses. Strip the insulation off a length of 10-12ga wire and interweave it among the foil, leaving it unattached towards the TFI end and grounding the other end to a suitable ground point. The foil insulates the wire from any interference. A trip to Radio Shack may be an easier route. They sell wire looms that will protect from any radio frequency interference and magnetic interference. Interference is obviously a bad thing, it can cause misfires if the TFI thinks it is getting the signal from the PIP to fire a plug. Install number tags to both ends of each wire so you know what's connecting to what later. Wrap your new harness in the salvaged foil. Neaten it all up with some 1/4" wire loom.

I don't understand what is being explained, what is this wire, why is this wire?
Any help will be appreciated.
