I'm just about to wire this T I'm building for my wife,I was wondering how many circuits I should use,the gauges of wire and sizes of fuses.Its a basic T no fancy dodads,maybe a stereo.I went to National T Bucket website but not enough info for me,I'm an idiot with wiring.
When I wired my T I got as many colors of 14 ga wire as I could find. Used 10 ga for the main leads from the starter, but 14 ga for everything else. I dont remember how many circuits it came out to be,, 6-7 I think but I got a 12 circuit fuse panel and store spare fuses in the unused ones. T's are very easy to wire, have fun!
JC Whitney has lots of different color wire in all sizes. I wired my T with the wire I bought from them and had no problems. Use a 12 guage for headlights-little overkill but you will have better lights. 10 guage for the ammeter and charging circuit. Rest can be 14.
