Sprinter Westfalia #133
My 2004 Sprinter (Westfalia conversion) has the factory towing hitch. I'm trying to add an electric brake controller for a trailer. I've researched other posts about this, and the problem is that under the driver's seat, I cannot find the wires to attach the brake controller to.
My factory 7-pin harness works properly for brake/turn signals/lights. I am trying to find the "blue" wire that is supposedly under the seat, to which I will wire the brake controller output. I do not see the trailer light control module under the seat. For that matter, I also need to find the brake wire under the seat to connect to.
Power should be easy--I assume I can grab that from the fat red battery terminal under the seat, correct?
I'm attaching a pic of the underseat area. Thanks to anyone who can help me sort this out!
