What Harness and any tips??

Thanks for all the input. Rather than jumping in and responding here and there. I decided to sit back and read and think about each piece of input. Now, I am 80% sure I am going to use the Speedway kit that I already have in my f100. Great kit and after ten years, no issues. 22 circuit $240. Not all that expensive compared to some of the kits.

- No I am not the best when it comes to electrical anything. I keep getting thrown at me, you don't learn by hiring it done. Now I know I mentioned hiring it done but that doesn't mean I will. Wiring frustrates the hell out of me and most people, as I have read. Which makes me want to tackle it myself.

- I want to replace ALL the wiring due to it being old, cracked, weathered, worn out, spliced, added onto, and so on. Its also almost 50 years old. Its truly a fire waiting to happen and poof the car is gone for good.

- I am not worried about factory appearance. It is already swapped to a BB, fuel cell, aftermarket gauges, and so on.

I came here looking for some input. I am not sure if I got exactly what I was looking for but I did get what I expected to. No worries I don't mean anything by that and I have taken no offense to any of what was said.

Thanks again!
I just got done rewiring a 72 Demon, I used Painless but have had some experience (all positive) with Speedway. Keep in mind I wired in a modern Hemi but much of the wiring is still same. Send me a PM if you want and I can send you some schematics I drew up on poster board so I could actually read the darn things. Best advice is go slow and be meticulous. Document what it is and what it will be. Your documentation will be invaluable for troubleshooting later. Ask me how I know! Hah!
