1975 Norton - Wiring Harness

I needed to create a new wiring harness for the bike. I had several upgrades/alterations in mind:

• 3 Phase Alternator
• Podtronics
• Trispark
• Relays for headlights and horn
• Fuse block
• Neg Ground
• LED Voltage Monitor to replace the assimilator
• Delete the kill switch
• Add a PowerPort
• Use an electronic flasher

I also wanted to use the original Norton wiring color scheme as much as possible. I obtained the request wire, bullet connectors and sleeves from Britishwiring.com

Jere is my attempt the diagram.

I first ran the wires on the bike in the approximate locations of everything. I left a lot of extra on each end and didn't terminate anything yet.  It took several go rounds to make sure I had all the wires run in the routes I wanted. I also added some extra ground wires in for the headlight, head, frame and rear tail. 

Starting to lay out the wiring

What a mess

Hmmm, what goes where?

Getting closer

Messy, just like the original

Custom turn signal stalks

Once I had the rough layout, I zip tied the thing together and removed it from the bike. I wrapped it in black harness tape and terminated with heat shrink. Then I remounted the loom on the frame and started cutting things to length and terminating. I slowly worked through the brake lights, head lights, indicator lights, turn signals (which took a while since I had to fabricate the mounts), and the ignition. 

I forgot to take pics of when I wrapped it and installed it.
