Elfmaze Posted September 30, 2014 (edited) I think I may have found the thing it was taped up behind the E brake peddle. BUT It had a red blue black and GREEN wire.... Is that the plug where the sub harness will plug into? Edit: I bought a harness for a 2007 nissan truck and it fits the plug. Looks like the colors are off but the guages look right... Just check for hot wire while the brakes are being pushed? the second one should have continuity through the 7 pin hitch?

Elfmaze Posted October 4, 2014 Ok I don't know if my nissna dealer was lying to me or just didn't know but the four wired plug was the brake controller. And I was able to buy a $9 sub harness from UHAUL for a 2007 Nissan Titan that fit and had the correct wires. 1 Forbes Davidson reacted to this Quote Share this post Link to post Share on other sites
