I have an '07 4runner that I want to install a hitch on. The problem is, I am finding no wiring kits for '07 4runners online. I am looking for a simple plug and play for a standard trailer, 4 pin. I have read some posts that the wiring is already there under the bumper, but I have not had a chance to look yet? This 4runner did not come with a tow package.... any advice? Uhaul wanted $309 to install the hitch with a 7 pin connector, but I can order a hitch for $150 delivered, and if my wiring is already there, and just needs an adapter, I just saved $150... any advice is appreciated!
