I have a donor harness, complete, I think but under my fuse box so only have the square C-1 in the center nothing else, is thus correct? Reason I am going to do my elimination of all wires, already had PCM flashed but don’t want to do all this and find out there is more wires I should of had attached underneath to my fuse box! Any info would be great! (Maybey I will only need C-1 after I eliminate, thx. If I decide to go w/stand-alone DBW harness WHO makes/sells the best one for the price?
