351w swap wiring question.. | Mustang Forums at StangNet
Aug 24, 2008Also, I have not cut any of the 5.0 EFI wiring harness yet & was wondering if anyone had template or drawings to show which wires to cut & which wires to keep? Or, would it be easier to just wire from scratch? I plan on using an MSD 6AL box, Ford Racing distributer & MSD coil.
