[32phil]

What I have done in the past with a few cars we have built is to use the original 32 headlight harness off the bottom of the steering column. I just bought one for a 32 pick up I'm finishing up. I add a fuse for the headlight circuit and one for the tail/brake light as well. Adding a 4 or 5 fuse panel helps to simplify adding fuses. Original 32s only had 1 fuse sooo a couple or 3 more is in order. That leaves the ignition circuit which on a flathead is pretty simple and you can use the original 32 dash harness as a start, adding or removing wires as needed. For the charging circuit I use a one wire Powergen and a Battery gauge instead of an ammeter.
I use old time Stewart Warner instruments with mechanical or electric senders. Add the instrument lights to the dash light switch and excite the gauges with 12V as needed.
By using the original (repro) wiring harness you start out with everything you need plus they are designed for 6V so they will handle the 12V with no problem.
