The 2005 owners manual says the truck has factory trailer wiring stored in the under body does someone know where and is it a 4 pin plug?

Answer 1

There was an answer posted about a Ford Escape, but it doesn't get to the Sequoia problem. I spent two weeks on the wiring issue, and here is the answer: I called Toyota USA and asked them to tell me where was the wire described in the manual. There isn't one. They don't know why they put that there, and it has been there since the 2003 model, but the said I could buy an after market piece. They are wrong. They simply assume that some aftermarket company makes them. But you can't buy the piece, you have to buy the entire towing wiring harness that runs from the battery back, disconnect the piece on the end near the tow hitch, and I guess, throw the rest away. They did this because they sell the towing package as a factory unit, and if you don't buy the factory unit new, they don't want you to be able to simply slap on the piece and save a couple hundred. Apparently, it's easier to install the whole wire, destroy the end piece and sell it as a non Limited Edition. The wiring harness is NOT sold except as a FULL UNIT. I tried with multiple dealers, wiring shops, nada. Getting the end piece from a wrecked Limited is a good idea, but they are near impossible to find. They also left out the fuse in the front, but you can get that at the dealer, it just snaps in. BUT THERE IS A WORK AROUND!!! Finally located a dealer that sells an add on unit that snaps into the turn signals. It's for the 2003, but it works on the 2004. It was the only way I could get towing lights. Look under 2003 part numbers. It does NOT snap into the junction that is underneath the chassis by the passenger rear wheel described in the manual. It must be installed in the turn signals.
