    When I purchased my Model S 85 D just over a year ago one of the big concessions I made when purchasing it was giving up my ability to tow trailers or use my trailer hitch bike rack. I knew there was an aftermarket trailer hitch option, but I was a little scared to take my Tesla apart, and I didn’t want to pay lots of money for someone else to do it. After researching it more I decided to take the plunge and DIY it. I had some great friends come help me which was helpful and I was able to make a video of how to do it. I found a couple other installation videos on YouTube for the Model S, but it was for the newer Model S. After hours of searching I found zero instructions on how to do the trailer wiring in my Model S! I hope this empowers others to be able to DIY the installation because it turned out to not be overly difficult in my opinion. I’ve now had it installed for nearly 3 months and I’ve loved the functionality it provides!

    In my case I also installed trailer light wiring (which was a lot more difficult to figure out, but I succeeded!) and now I’ve been able to take our small 14 foot fishing boat to multiple lakes, I’ve towed a small camping trailer, small utility trailer, large utility trailer and used our trailer hitch bike rack. I highly recommend doing it if you’ve ever thought it would be useful functionality to have. Feel free to ask any questions you may have and I’ll do the best I can to answer them based on my experience.

    This is a video I created on the why, parts and costs associated with the installation

    This is my trailer hitch installation instruction video

    I've had one (hitch) sitting on my porch for a good 3 months, so thank you much for the video!

    I already have this hitch installed, and you're right, the wiring was frustrating. You would think the wiring would be easy.

    What is the heaviest trailer you have towed? It is rated at 2,000 pounds total, with 200 pounds tongue weight.

    On a recent tow, I guess that it was 2,200 pounds. The energy consumption was roughly 2.5 times without a trailer.

    I don't exactly know the weight of any of the trailers I've towed, but the heaviest is the small 14 foot fiberglass bass boat in the pictures above. One of these days I need to tow it to a scale somewhere to weigh it.

    FYI the tongue weight (at least for my hitch) is 300 lbs not 200 lbs.

    I just installed mine too. I’ve had a heck of a time trying to actually buy a hitch rack this year!
