Prius Plug in Towing

Has anyone towed anything with their Prius Plug In? If so, how many lbs have you tried and what wiring harness did you use?
thx,

Thx for the response, agreed it would only be a small trailer with a row boat or something to that effect 500 lbs max. However, it seems that there is some conflicting information about tow hitch wiring harnesses. I have already installed the Curt tow bar assembly for the Prius, but just now came to find out that the Curt wire harness I bought excludes the plug in for assembly. There is another company called Tow Ready that makes a harness as well, but even though their customer service told me it would work, their website says it will not. It could be that because we have plug in Prius's that there is no electrical harness that can make a trailer light up with our cars

 

No I wasn't at the Deer Park Home Depot this passed weekend.
Thank you everyone for the great responses. I put on my tow hitch, hooked up my little trailer, weighs 440 lbs, and added a plastic pontoon boat 145 lbs and towed it around all July 4th weekend. Dropped the boat into several lakes in Patchogue NY. The car and hitch and trailer performed perfectly (went without a hitch, sorry). I have not yet hooked up the wiring harness, but the boat sits lower than my own tail lights. I am going to hook it up today or tomorrow and will report back. I have both the Curt wiring harness and the Tow Ready wiring harness. Not sure which I will use yet, but I will report back on how it works out.

 

Sorry Bisco didn't see your request for pics until after I finished the wiring harness install, but I will post a few pics of my prius with the hitch, and trailer with my boat on it. I promise. Happy to report that this lighting harness install was not much trouble at all. I used the Curt T-Connector lighting harness model # 56147 which is actually for the regular Prius. I am sure that the Tow Ready model would have worked as well. The manufacturer says it will not work with the Plug In, however, as others on here have stated on here, this is just to cover their own behinds because we have an electric car right. Anyway, you take apart most of the trunk area to get to the wires and battery, not the Huge Space Odessey battery that is in the middle of our trunks, but the normal battery which we have as well, which is behind the passenger side rear side panels in the trunk. This install took about 30 minutes to complete. I had to call a friend midway because I needed a third hand to hold back the rear panels while I was connected the wires. It works like its supposed to, my trailer lights are working, now I don't have to worry about the police pulling me over for this. Thanks again for all the quick support on here folks!!
