I am attempting to make a minor mod that will change my life.... I recently got my first pickup and added a toolbox (Weatherguard saddle box). Love the setup, but one complaint is no power locks on the toolbox. Looking at the Weatherguard lock it is an extremely simple design. I have engineered a way to add a solenoid and make it work but just need to tap into the lock / unlock wire. Once i get everything working i will try and post a how-to so others can do it. My Question: Which wire in the harness going to the tailgate controls the lock/unlock. Appears to be about 6 or 8 wires in the harness. I assume most are for the camera and only two are for the lock. Any ideas how to ID which wires are the lock. If i had 8 hands i would fire the lock/unlock while i measure each wire in the harness but that would take a while -especially if there are 8 and i have to find the two reversing polarity on lock/unlock. Thanks in advance,
