    I will find that out on Wednesday. I know they sell the T connector that is plug and play for $40-50 on Amazon or eBay. If you go that route there is no splicing needed. I am probably going to get the universal kit from my local auto parts store for $5 and I can have one of the guys install it for about $20.

    I have had a hitch for three years. Tow utility trailers and my 475 lb sailboat plus trailer regularly. No problem. I won't tow our 1900 lb camper except a few miles, slowly. Big demand on the drive system and and brakes have much more work to do with a trailer and load over 1,000 lbs. I think of 1,500 lbs as a limit if there aren't too many hills or high temps.

    I just had the hitch installed this passed weekend. I will post pictures when I tow something with it most likely in the next week.

    Whoa--I wouldn't even think about doing this. That's a lot of trailer for a car that is not intended to tow at all. We have an 18' open bow in the family--about 2200 lbs with the trailer, and it's a pretty good workout for the body-on-frame 4runner we use. You definitely know it's there. It increases stopping distance dramatically and some of the jounces on highway bumps are pretty scary. Boat trailers have the axle(s) pretty far back and although resting tongue load is still fairly light, the forces the boat trailer puts on the hitch while going over bumps can be pretty severe. It's enough to cause a loss of control, even with a vehicle rated for twice the towing load.

    I really hope you reconsider. I've heard the Highlander Hybrid is a nice tow rig, and it's rated to tow a fair bit. Please don't use the Prius, for your own safety and the safety of others.

    I have a highlander hybrid too but I am selling it and replacing it with a Chevy express. I already installed a hitch on the express for when I start using it. Until now I have towed it with my friends GMC Sierra and you don't even notice it's there. Mine weights somewhere between 1700 and 1900 pounds on the trailer with a full tank of fuel and all gear.

    I regularly tow a caravan at around 2240 lbs without problems, but the maximum gross weight for the van is actually 2360 lbs . This van also has a large frontal area "wind resistance". I tow at sensible speeds "maximum 50 mph on normal roads 60 mph on motorways" and have climbed hills up to 1 in 5 (20%). Fuel consumption has averaged at 49 mpg UK gallons. I tow with a hitch weight of 130 lbs.
    The car is a 2008 at 110,000 miles, and the outfit is shown below.
    While certainly not the best tow car I have driven in the last 50 years, it is by no means the worst.

    I am picking up my new 24' trailer next week. I will post a pic then. Anyone know how to install the wire harness for the trailer lights? I bought a universal one which has to be tapped into the taillights.

    done laughing, towing a boat is serious, launch ramps etc. wet/steep inclines etc. hauling leaves 2 dump probly ok. if you r going 2 do it at least try 2 balance as much as possible with your car. briprius rig looks kewl but euro stuff is made for smaller cars/tite spaces. seriously.

    I towed it home and it handle fine even at 85 mph. I ended up doing a quick wiring job myself while the dealer ran to get the title notorized. It turns out the 4 pin doesn't work with the prius because the break lights are separate from the turn signals. So I had turn signals, and running lights but no break lights. I drove about 6 hours with no problems except the battery would run a little low climing up the mountains but I reduce my speed on those parts. I have pictures which I will try and load.

    That doesn't seem very logical, lol. I'd change it.

    I'm not sure of gen II transaxle fluid change details, would think it's similar to gen III. Maybe gen II owners can chime in, provide some links/info?

    I would change it for a number of reasons. The fluid in the Prius transmission does three actions.
    (1) Lubricates all the bearings and gear train.
    (2) Acts as a coolant transfer medium.
    (3) Acts as an insulator for the High voltage winding's on the mg's.
    The fluid if not changed carries round metal particles from the ware in process. These in the long term can damage the bearings and winding insulation as well as making the oil more conductive to the high voltages used in the transmission. The oil looses it's viscosity over a period of 30,000 miles. Proven by oil analyse on many occasions here on PC.

    I'm thinking the OP should phone his insurance company and check if they cover him considering Prius is not approved to tow anything.
    I do have an 18 feet boat myself and the boat/trailer combo is over 3000 lbs loaded with fuel and gear. I would be especially concerned about prius pulled into water on steep wet and slippery boat launch.

    The Prius isn't made for towing, but it depends on the weight of the load and the grade of hill. I don't think it would be hard to tell if your Prius is balking at the load. Test it out (gently) for awhile, and there's your answer.

    I understand that cars sold in Europe and Australia have more allowance for towing compared to USA.
    So, John, what is the official towing capacity for Prius in UK?

    The same as the US zero. I do not know the regulations in the US as far as brakes are concerned as some comments have been made that braking when towing is very poor. In the UK if a trailer is over a given weight it must have it's own braking system. In the case of the caravan that I tow the caravan brakes stop the car better when towing than when the car is solo.
