Wiring 101.

Hey Guys,

I am installing a new wiring harness this week. just a couple basic wiring / commando wiring questions... As reference, i have the CNW turn signals, Sparx III rotor stator and Boyer ignition. 74 commando.

1 - There are a bunch of excess wires, i would assume they are for the interceptor. When cutting off the excess can i just cut them at the base of the harness and use electrical tape to hide them or do i need to keep the ends on them and tape them up to the harness?

2 - What connections do you recommend? I know there will be lots of opinions but currently the new harness mainly has the bullet ends, where the previous headlight harness appears to have been permanently connected and had heat shrink over it.

3 - Has anyone seen a wiring diagram that shows the modern upgrades that many of us have (Boyer, Sparx etc.)?

4 - Where do you buy your electrical supplies (US)?

5 - Last but not least, with the excess wires there are a lot of extra grounds (red wires). Do these all need to be grounded? When referencing my previous harness (custom made) it just didn't have them or the excess wiring.

thanks guys.

Joe, most not back at work desks yet.

1. Looms are excess police wired, radio, lights, siren etc, about half a shoe box worth. Once a useless loop or lead is ID'd do what ever ya like with it as its not hooked to anything on either end.

2. I prefer a fresh Lucas bullet, but to repair a bad wire terminal is a task to match factory robustness and extra tools too. A new loom should avoid that so I vote stick with Lucas. Otherwise crimp spades show up most often as handy good enough.

3. There are no changes to loom to install fancy ignitions or chargers, just plug and play. Dual Coils re-connected is about the extent of Boyer changes.

4. About any major Brit Iron Vendor but online sites too.

5. See #1 above. Most the excess copper's copper are red ground leads and loops some with two or three red earths ends connected in common and at least one that's a loop as long as the frame spine with like 3-4 ends, but none of this is electrically hooked up to anything, just dead weight clutter

Good hunting, test lighting and untangling to re wrapping meditations to you.
You have opportunity to wire up some bar switches to your liking too.
Avoid black electric tape as turns to goo under then un ravels like trailer trash wiring. I like the stick-meld to itself silycon wrap where needed.
