Review on CURT 56331 Custom 4-Pin Trailer Wiring Harness, Vehicle-Side, Compatible with Chrysler Town and Country, Dodge Grand Caravan, in Black by Chris Burns

Great overall wiring. Setup was easy and quick with video searches. You have to drill a converter box screw into the wall of the car behind the taillight, but that didn't cause any problems or visible cosmetic issues (since it's not visible after the taillight is reinstalled). There are several kits. out there that look like they're using speaker wire, even though it's a thicker gauge. My problem was routing the wire from the bottom of the car to the battery. My suggestion would be to start the battery cable by routing it from the battery and back to the taillight. Getting it through the engine bay wasn't easy (I used an old wire hanger, lowered it with a small hook and tied the battery cable to it, then carefully pulled it back).
