Buying tow hitch

It could be the wiring. My wife has a Honda Pilot and I looked at wiring it a few years ago and the wire harness alone we something like $250. Gulp.

But I see lawrosa posted above a link for the wiring, but OP you should ask and make sure that will fit correctly. If so, should be an easy and inexpensive install.

Thats crazy... That highlander most likely has the harness already installed. Just need the hitch.. Dont know what else comes with the tow package on that truck...

Anyways for 175$ you can get a hitch... The truck only can tow 5000 so this is over kill..

I wouldnt waste money on the factory hitch..

You can install this yourself in probably 30 minutes.. Then go to a trailer place and get the 7 way installed if needed. But you probably have a plug and play..

Brake controller if you get one is plug and play too most likely..

Installed this price is just right

More important than esthetics is functionality and weight capacity ratings for a hitch.

$1000+ for a hitch and basic wiring seems a lot, but I admit I haven't priced something like that for awhile. I'd shop around. U-Haul installs hitches, most all RV dealers and you may even have a hitch specialty outfit in your area....
