Installed a couple of things, one useful, one a bit more cosmetic-
I installed a dual USB plug in my center console. The 4Runner sorely lacks some USB plugs and the one provided in the front dash for audio input can charge, but is woefully low powered. I've been using the cigarette lighter and eyeing the two blank buttons in my center console so I finally bought a dual USB plug and installed it-
I tapped electrical off the dash cigarette/12v and ran the wires inside the console to the button blank. I had to fiddle with and replace a faulty connector the plug came with, but it works now and I am pleased. Note the rubber flap to keep crap out of the plugs (not like I let the inside get dirty or anything...).
In the back I also installed something a bit unnecessary but I just liked the idea. It's a cover for the rear passenger storage compartment near the back hatch-
Before (note the metal latch catch already installed in the top center of the space).
After.
It's a nifty little add-on that cleans up the back. The large cover pops off with a press of a button, and the lower one can be popped out from the inside. I'm happy.
On the other side of things that matter- I recently got a new battery, 4 new Cooper Discoverer tires, and got a full engine tune up and sway bar links and bushings (the bushings were gone...). Soon will be a full deep clean and detail and she'll be lookin' pretty good out there again.
