I have done some relocation of my turn signal, coil, ignition switch, tail light, and mini apes requiring adding on to the control wiring. I used acid core solder. And, now I've read that ot isn't the best to use on electrical wires. I haven't had any problems with breakage except one front turn signal wire broke at the joint. But that was because everytime the bike was parked the forks fell to that side and then iI would straighten it out to ride. Over a period of time it just broke. The other wires are straight and taped or zip tied to the frame.
