Simple Wiring

I did this to my first HD (1980 Super Glide). It was posted in a issue of Easy Rider. Essentially it was wiring for dummies. You had the OEM wiring harness pulled off the bike and wired up everything clean. It made tracking electrical problems much easier to trace and fix.

I know that electronic things have come a long way but.... I'm thinking if you remove some of the things that are "extra" (i.e. kick stand sensor ans what not) and leave only the "essentials" (i.e. ignition components, lights, horn, etc) you could probably clean up the wiring harness a lot.

Opinions, thoughts, comments?

My thought would be (if you don't actually have any electrical problems), if it ain't broke, don't fix it.

The LC FAB "chopper" diagram cuts out most of the frilly crap and if just used as a reference to connections,[my take on a custom harness],REALLY cleans up the bike..
my harness to the front of the bike.

Ruining a perfectly good Bonnie since 2004.

There are a pile of threads on cutting down the stock harness.

If you want to start from scratch, I'd bet the LC diagram is worth the ten bucks. I've never seen one, but it sounds like it does a pretty good job of explaining how the various parts need to be connected.

Having probably drawn fifty diagrams for different setups on Hinckley twins, and I threw this one together for a project some time ago as a "safe" (meaning it keeps the oil pressure light and TPS) minimum wiring diagram:

It has a horn and lights, but no turn signals. It does not have a starter solenoid, but calls for a high-amp foot switch, which is probably not the best idea, but it eliminates a lot of wire.

To give you an idea of just how little wire that is, here's a diagram for a moderately cut-down EFI bike:

(It's still in-progress.)

A stock carb bike probably has a comparable amount of wire.

Feel free to hit me with a PM with any specific questions, but be warned that I'm not on the board all that often, so it may take a while for me to reply.
