where did you drill the holes in your frame?View attachment 97034 This is how I hid my 12v 7ah battery. Also I run my wiring inside my frame, but I make sure that it does not effect the frame integrety.
You can buy rolls of heat shrink tubing from harbor freight for a coupla bucks.
Run all your wires nice and straight thru the tubing, keep your solder joints clean and small, then use small zip ties and run the wiring alongside of your brake cables, clutch cables, whatever.
I've run wires underneath my fenders with duct tape, and behind fender struts with krazy glue.
Nothing bugs me more than bikes with loose wires, too-long cables, and tons of zip ties cluttering it up.
