Usually I'll use 16 gauge. But, most manufacturers are using a lot lighter gauge. My 2006 Ducati ST uses what looks like 20 or 22 for the heated grips.
You could run them straight off the battery. Just make sure there’s a fuse in line. In regards to the heat, I’ve never used the Oxford ones but full power is warm enough for me to feel it through my winter gloves.
@@stevegsgarage”Just make sure there’s a fuse in line.” Can you elaborate on what this means or how to achieve it? I just ordered these. The most electrical work I’ve done is installing LED and run them straight to the battery. Those lights came with a fuse. Does this grip kit?
