I'm relocating my TFI to the fender, using a setup from a mid 90's F-series. I have the distributor and the piece of harness that plugs into the stator. My question is about the shielded wiring involved. Is it just there to prevent radio noise, or does it prevent interference with the PIP signal back to the PCM? I don't have a stereo in my car, and if that's the only issue I can just spice into the harness to extend it, but if it's going to cause any other problems I'll have to figure out how to properly shield the new section of wire.
