Is there no existing wire under the seat that runs back to the trailer socket? Or am I misreading this. I was under the impression the BC would feed to an existing line under the driver seat and not have to be ran all the way back to the harness.
Yeah I am in a constant battle with previous owner adaptations... Everything appears to be connected correctly, just oddly. It is a mess up there and that's a project for another day. Just trying to figure out the trailer wiring right now.That's an interesting photo ... compared to the OEM battery (and the proper-sized replacements) your positive and negative posts are on the "wrong side" of the battery.
On the "correct" battery they on the side towards the center of the Sprinter, not the outer.
