Hey everyone! Happy to be here on the forum.
I'm rewiring a new harness for my 80' XS1100 SH (based on the 4R0 VIN, I believe its an early 81' SH). The bike was previously owned as a partially built cafe racer project that I've been finishing.
The original wiring harness was heavily modified by the prior owner and suffered a lot of leaks/drains - the battery would drain after a day. I've rewired nearly all of the wiring harness but can't figure out how to get a spark from the TCI with the wiring diagrams I've found online, in conjunction with the M.Unit Blue. The starter runs fine when giving run a push, but she's not igniting afterwards. Looking at wiring diagrams there's a red and black wire I can't figure, as well as several wires previously missing from the connector. Additionally, I can't for the life of me figure the wiring for the three-way turn signal switch and high/low lights to run to the M.Unit from an M.Button system, in Config C. I can get both R/L to fire at the same time... but not separately.
Any advice would be appreciated.
