Assuming you're trying to get power to your GPS on your bars. I put a 12v power (cig lighter type) supply in the front of my left box & ran the wire under the lip of the cover by cutting a rounded grove / notch (used a round file), a little bigger than the wire. Open & close, no problem. So far so good.
I use a marine grade (ebay) outlet, put it in the lower fwd part of the box. Note you need to keep it fairly close to the bottom for clearance. You might have to angle the front in first to get clearance for it to drop in.
Don't know if this helps. Not sure what you're asking.
