it i cut it down to fit it through one of the mounting holes, and get rid of the excess wire, and at the same time i wired in a visor homelink unit that i waterproofed with plasti dip. it all plugs into my battery tender lead, and is all fitted behind the battery box, so all i need to do is unplug the lead, and the battery cover pops off like normal. You cant see the homelink unless you are looking for it as well, the battery bag lip just covers it a shade

OH and you can see the new pipe that got put on yesterday

here are a couple pics, i will get one of the charger up later.

 

That's a good idea. Good job!

 

Nice! I've thought about adding a charger but never liked the ones that mount to the bars. That is a sweet way of doing it. Also gives you a place to hold your phone or whatever else you want to charge.

 

very nice!
