i did the OEM tow hitch install today,pretty easy with help from on line photos.the toyota instruction sheet is weak,so color photos really helped.i saved the link if anyone needs it.
the bumper comes off pretty easy,but it feels like it's gonna break,scarey.i had to paint the trim piece black,and i broke one of the snaps on the old one(taking it off)but it got replaced anyway.
The biggest problem I had with this install was how/where to mount the electrical. With the stock rear skid plate, mounting it on the bottom of the bumper was not an option. After much cussing, banging my head on the side of the truck and a couple beers, I realized that there is a mounting bracket attached to the skid plate. Doh!
This is a fairly easy mod even for those of us who aren't so great with a set of wrenches. I was glad I tackled it on my own instead of paying the dealer nearly $600! Terry's right, the color pics from the internet were far more helpful than the included instructions.
Thats true.. I had the same problem mounth the 4 pin. I need to get some kind of bracket. For now I am just using the mounting bolt from the harness wire bundle. Its not perfect but it works..
