Hi all. I have an 05 Tacoma V6 with the towing package and have bought a Tekn osha XP Voyager controller. I have wired up a few of these in the past but not with a harness to connect to like we have.
My question is regarding the small gauge brown ground wire that is part of the pigtail that came in the glove box. Do I hook up the white 14 ga. ground wire coming out of my controller to the little 18 ga. brown ground wire on the pigtail? Hooking a 14 ga. wire to a 18 ga. wire on a primary power circuit just goes against my grain, so I could use a little clarification. I did read the towing bible but just want to make sure. Thanks in advance for any help on this.
