In the middle of all this I find a terminated, permanent live, heavy gauge wire coming back as far as the top of the airbox with the redundant third phase loop and the oil pressure switch wire. What is going on ?

Mystery permanent live wire ?
Today I removed the regulator +ve from the battery +ve and spliced it into the red wire downstream of the main fuse because I find Posplayr's argument about splitting currents convincing. The bike runs better.

I haven't connected my hot R&R lead into the main harness yet, I'm still connected to the battery direct but my R&R is clear up front which means a voltage drop over the long wire length even though it is 10 gauge wire. Maybe I'm overthinking it, but to splice into the harness conmecting it to the smaller gauge wire seems like we'd get less voltage at the battery from the R&R?----------------------------------------------------------------

Not sure why the bike would be running alot better except if you could see that you improved your voltages with the change.

That is where you should attach the R/R +ve. If you found another spot down stream of the 15 amp fuse then you probably attached it to the exact same spot as the wire you are looking at. You can cut it back and tape it over as it is now not needed anymore.

If I understand correctly it is the original Tee. Hard to explain the better running. It feels sharper on the throttle low down. Probably better voltage to the ignition. Someone has had a real go at this harness and the only way is up. Just found four domestic screw type connectors on the coil supply. Is there no end to the ingenuity of POs.
If you did a coil relay mod, you would want to power it from the "T" as well.

Thanks a lot for that again. Thats the way I have it set up now. Today's excitement is finding a Scotchlock on the orange return wire at the ign switch.!!!?? There are times when I think a total rewire is going to be easier but I know better than that
Relays are in the future especially the headlight as over here we have the added bonus of an on/off switch. I'm losing 0.8V at the bulb. Who knows maybe with the scotchlock sorted things will improve.97 R1100R
