hello..I have an 01 tundra that I am trying to get ready to tow a trailer. Well I have a few issues. I can't seem to get the lights to work. I bought my truck pretty stock without a tow package so no hitch or anything. Got a hitch, and I bought the factory toyota 4 pigtail wire harness that plugs into the plug above my license plate, but I still don't get nothing. So my question is do I need a converter? How do I tell if I have one? Also, I don't have the tow kit that is located on my fuse box? I am also confused about the fuse? Where do I need a fuse in the box? There is a lot of locations? I guess I am not that savvy about this....sheesh this is headache to get a trailer working. I just want to tow my dirtbikes! nothing special.....sorry another question. What is the large harness that is dangling from my drivers side rear bumper? it looks like a 7 or 9 pin connector. What is that for? Your help would be super appreciated!! Thank you.
