Instrument engineer returned from his cruise. He worked with me half a day today, but he had to leave because of a sinus infection. By God's grace and four (4) wiring diagrams I figured out the dash harness. I connected the entire dash, and I have 50% of the dash harness marked for removal (heater, wipers, tach, speedo, wiper pump, useless switches, etc).
Completed so far:
Engine bay harness
ECU
Test plugs (2)
Dash harness
Things left to do:
Complete wiring for factory Hayabusa fuse box/relays
Remove unnecessary dash plugs/wiring
Must... be... patient...
