Maybe there is someone who already went though the harness dissection and has a 'required inventory list' of wire by color needed to fabricate a new harness?

I have Boyer and other non-OEM switched etc. to custom wire but a raw wire material list would sure be useful. I don't want to buy 50 feet of each color...nor do I really want to dissect and inventory, but I will.

Or I'll buy an inventory of several plain colors and draw a new diagram for posterity...

Engine rebuilt, frame coated, now going back together!

Thanks

Jeff

When I rewired my Bitsa project, I couldn't find the correctly colored wires locally. I didn't really try very hard since I am also runing Sparx ignition and rectifier/regulator, the stock harness was going to be modified anyway. I just made up a new diagram with the new different colored wires. Sorry, but I didn't measure what I used. Probably wouldn't help much anyway since I relocated where components were attached in the system (ignition switch, light switch, coils, regulator/rectifier, EI box have all been relocated).

So what you are trying to say is "You're no freakin' help!!!!" :-P

I'm red/green colorblind, so I'm a big fan of wiring numbers. You can go to an electrical supply house and get a book of peel and stick wiring numbers that you can attach to mating wires/terminals. Ths would allow you to get one spool of wire and wire the entire bike with it. Just a thought if keeping costs down is a goal. All black wire would also help make it disappear on a black frame.

I still use wire numbers even though I can drag the wife out to help me with the colors. Some diagrams have errors and putting the numbers on each wire before I disconnect certainly makes life easy when I reconnect them.

I bought some white heat shrink and wrote the name of the component the wire was to be connected too with a fine black Sharpie before slipping it over the wire and crimping the end on. When heated the letters shrink too but are still legible. I rubbed them and they seem permanent. I guess you could do numbers if you wanted to.

I just re-wired my 68 Bonnie. I bought a NOS cloth harness and am running Sparx EI and alternator. So, at least 33% of the original wires arent used. I also add my own ground wires to a single point (SPG).
If I was to do this again, I would buy the NOS harness, cut the cover off it, strip out all the wires I dont need, add the new EI and alternator wires and Ground wires, then tape it all up!!!
Hope this helps.

Hi Rob,
I'm colourblind too, although I don't have too many problems with the wire colours provided I have good lighting (I normally keep a small flashlight close to hand!) Your idea about the numbers is a good one, the same system is used in aircraft wiring, normally all the wires are white.

Great tips. Thanks guys. I'm actually looking fwd to getting into the wiring, something therapeutic about it for me.

I'll use numbers on white or yellow heat shrink so I can just add numbers to the wiring diagram if I override a color code.

Full harness rebuild with single point ground and separate fused circuits.

I can't take credit for it, Webby. I've spent my career in the Power Plant industry and everything is by wire number. When I was a kid, I fried a few things on a 450 Honda because I tried to reconnect everything by myself. When the smoke cleared and I dug into my pocket for the few new parts, I embarrassingly asked my Mom to come out and help me reconnect the wires.

Rob
