I need to power my GPS with a cigarette lighter outlet but there is no easy mounting place on a motorcycle.
I wired a cigarette lighter outlet directly to the battery through a fuse then ran it out from under the seat and taped it to the left side of gas tank. My Navman iCN 510 GPS resides on my tank bag and powered from this lighter outlet. Not the best position but it works.
The power connection for the Widder heated vest also came out of the battery, under the seat then to the right side of the gas tank.
While wiring the cigarette lighter outlet, I found that 1 of the wires to power my Widder vest was half-broken after 7 years. I cut off the ring, resoldered a new ring on it and it's as good as new.
