Re: Toyota Sienna Draw-Tite Max-Frame Trailer Hitch Receiver Class III - 2"
So next up would be a wiring interface module. I really prefer a 'buffered' type when possible, so that a trailer wiring issue won't propagate into the vehicle. In addition to the signals from the running/brake/directionals, this type of module requires a 12v feed from the battery, and uses virtually no power from the vehicles lighting system. If something shorts out, you only blow the fuse on the feed, and your van lights stay on.
A ready available single point trailer hitch extension connector with a power feed was provided on my Subaru, but I doubt Toyota is as generous. At least they weren't on my Gen-II. So step one is likely to do as Geezer did and run a fresh line to the back. Pro's & con's of the different brand interface modules? If I want to run a line out permanently, any good tips on existing rubber body plugs? I hate drilling....
