Alright so I went led crazy and installed a bunch of LEDs and stuff.
First was some led back up lights. They're wired separately from the reverse circuit, so that when the key is in acc mode, I can turn the lights on if I need to. I used a Oem Toyota switch that I bought on Amazon and the lights are from Amazon too. If there's one thing I've learned from this, it's that next time I'm just making my own harness and soldering everything rather than buying a pre made harness, and having to still customize everything about it. The only reason I bought a pre made harness is cause I didn't know how to hook up a relay but through this experience I've learned and I'll make my harnesses from now on.
So on to the install, first off I had to take off the bumper to run the wires how I wanted to. Once you get the bumper off there's a cemt type thing on the side that you can fish wires through. It's kinda difficult cause it's a tight are but it worked out nicely.
Next was mounting the lights and wiring them up. The connectors on the preside harness I bought wound up breaking off and wires bending so I put on new ones and used a bunch of heat shrink to make sure no moisture or dirt found its way into the connections.
Then I put some protective plastic conduit around the wires just for a little abrasion resistance and zip tied everything in place.
One thing to note, leave a little slack in the line so you can take the light off the mount to re mount the bumper. Once that's done put the bumper back on and mount the lights. I mounted mine where the oem bumper attaches to the mount or whatever, like this.
Next I installed the relay and the ground, I did it here
Then you run all the wires down the side of truck and under the door kick panels. I used an add a circuit for power; only pulls like 3 or 4 amps, but I plan on installing a blue sea fuse box sometime in the future.
Then you wire up the switch, here's the one I used
And there you go, you have back up lights. They're pretty freakin bright. No excuses for backing into stuff now.
