Drill holes
that's what I did, I drilled a small hole in the A pillar below the main wiring plug, then zip tied the wires to the rubber tube running to the door and then cut a small hole in the rubber tube where it enters the door.
You could (possibly) drill out a part of the big connector plug thing and feed the wires through there. Depends if you have any space free in the connector block.
The connector will twist off - you'll need some big grips to take it off tho!
