Wiring for pick ups on timing advance

[Joe_L]

I got a used timing advance on eBay and I need help hooking up the harness. The harness on my 1980 xs1100s from the plug to the igniter is set up just like the wiring diagram in the manual. It has 4 wires, red/white, green/white, yellow/red and yellow/green. The harness from the plug to the pick up coils is all together different. It has 4 wires, blue, blue, orange and grey. The plug was cut off and I have to re-wire. I don't know how to proceed. The wires coming from the pick ups are original, but how do I match them up to the plug going to the igniter?

Does this help?

Rewire advance

Greg,
Thanks for the help. The sky blue in the middle is the neutral light. I have 2 light blue, 1 orange and a grey on mine. Still some questions, but I can move on from here.
Thanks again,
Joe

Rewire

Greg,
The guy that refurbished mine must know something because the wires he used to replace the ones that were cut off are blue,black, orange and grey, just like yours. That is where I will begin.
You're the best,
Joe

Hi Joe_L, here's some more pics, the last two show how I removed and isolated the neutral wire from the pickup coil harness. HTH
