Finally sorted out that Anderson plug at the back. The Traxide system, whilst perfect otherwise, always bothered me for the rear untidy look of the cable hanging out.
Stole this idea from a Facebook post.
First removed the white 12S plug - unplugged its plug below the left tail light, then fed that cable out through the mounting hole. No cutting, and can be restored to factory without any drama.
Rerun the traxide cable up over the top of the bumper steel, then out the hole. I had an older cable too, so wired that up for now, but will likely change out for a red Anderson later, leading to a mppt controller.
Mounted the two Anderson plugs into the eledric plate, then bolted straight into the same bolt holes the 12S plug was using. Aligns perfectly, and fits the threaded holes with the included stainless bolts. Incredible luck there!
Anyway, pretty pleased with the result, for an amateur like me :-)
