I used a Posi-Tap connector off the Black/Green wire coming out the back of the fuse block for my switched 12v. But be careful. There are 2 Black/Green wires. One is coming off fuse D which is for the headlights, turn lights and horn. I think it was fuse 3 as labeled on the fuse block lid. DON'T use the other B/G wire which is fuse 1 for ABS IGN. Don't mess with anything related to ABS. I also NEVER use a tap off any factory wire to directly provide power to anything I add. Instead I use the tap for a relay trigger, and that relay gets power directly from the battery. This minimizes any load added to the factory systems. Important since the factory sizes wires only for the load they intend to put on those systems. Also, doing it this way allows me to power not only the LED light bar I added but also the Uni-Go trailer lighting as well without adding any noticeable load on the factory systems.
This is super helpful, Bob! Thanks! I do like the idea of tapping into a wire just for trigger purposes. You're pointing out one at the fuse block so that should be pretty straightforward. I may use an add-a-circuit fuse holder so I don't actually tap into any wires. In the past, I've done that and installed a solid state relay with the actual power coming straight from the battery. Of course, battery draw for a phone or gps is pretty small but still, I think this is a great way to go. Thanks again! --Ken
BTW, on this forum, what do you use for photo hosting? Or, can I just use the "insert image" button?
