I used an old heatsink from the 60's that came out of an amplifier. The tfi module is mounted under the heatsink. The heatsink is mounted to a two sided aluminum box. I put under where the stock air box was. I had to extend the tfi wires with the grey plug about 1 foot, 3 of the 6 wires were shielded by ford, so i shielded with heavy duty aluminum foil the extended wires to the heatsink. The three wires from the tfi module to the distributor i ran up the fender to the firewall, along the firewall and back under the upper intake to the distributor, of these 3 wires only one gets shielded, that one is the pip signal wire, the pip connector on the tfi module is closest to the grey plug in, the middle connector is power and the furthest connector from the plug end is ground. I made my own shielded wire by wrapping regular insulated 16 gauge wire with smaller bare wire leaving a pigtail on one end, then wrapping that with heavy duty aluminum foil, then wrap all that with electrical tape, solder the female connectors on the three wires, connect to tfi module and run them to the distributor, grounding the shielded wire pigtail to the chassis. If you cut any wires, number them first with masking tape.
