I have no idea if this will apply to you but I just relocated my turn signals on my 650 Custom and all the connectors were inside the taillight. It was VERY convenient as I didn't want to cut and splice either.
There were three nuts holding the tail light assy inside the fender, a little difficult to locate (ended up removing the fender to find them).
I hope this helps
