Pictures like that make me want to run an m-unit haha
That was the front there was a similar mess in the rear but it was easier. I have to tell ya, I can do just about anything in building these bikes. I have accomplished much more difficult mods, build custom parts from scratch and making ridiculous things fit in these vintage bikes; but this wiring takes the cake as far as pain and frustration.
My brain understands making a harness work, but hiding the wires and rerouting them, etc has been the most painful exercise I have ever done in any of my builds so far. Maybe its just me but I had some pretty frustrating days the previous week. I'm super glad I have the universal ultima solution for my cafe xv. The custom solution would definitely be easier than the modding the stock harness. I actually regretted after I was down the path that I didn't go custom for this bike too. The hours I have into it would have paid for any of these custom solutions.
For the front mess, I relocated the fuse block into the frame. Cut more wires that had extra length. Cut out the h4 connector. Swapped out the stock rhd assembly with a gsxr throttle and a push button momentary switch
