Order this part from HDL or any Honda shop. It original was made for an older Gold Wing.
You will have to move 1 wire in the plug to match yours. It also has a bigger boot.
My bike got one 2 or 3 years ago now, and it still works fine.

From what i'm reading between the lines here, is you have a heavy draw on some added lights. Right? Move the connection off of the headlight/starter circuit.
