wow how did you get the junction box in there?

It seems as though the wires an either pass through the two holes in the front of the plug-in (but it looks like they need to be taped to the bar so they dont 'flap around' or look untidy....or can pass through the rear of the aerobar itself down into the stem area (so better cut the length right) correct?

thanks for the pics, these are helpful
edit: do the speedshop bars have an exit point on the aerobar or did you drill a small hol in that area to allow the wire to come out? because its very conveniently placed lol
