The wiring for me has been the most challenging part of the build. Not so much making things work but more about making sense of it all. I can't say good enough things about the RF harness. I pulled the Mustang OEM harness out of my donor and got a big lump in my throat with the thought of the mountain I would have to climb in trying to understand it all. There are some areas in the RF manual that could use some further clarification but for the most part, I was able to find all my answers on this forum or a call to RF.

I'm at that stage in the wiring where I am adding personal touches such as courtesy lights under the dash, power sockets, etc. If you thought your "fist start" was a good feeling, wait until your turn signals, hazard lights, flash to pass, low beam, high beam, not to mention your gauges all working.
