Roy Lee E from Sellersville, PA said, "I installed the Curt T-Connector on my 2004 Lexus RX330 last week and it works great. I didn't exactly follow the provided instructions, but instead found Lexus directions for installing their wiring harness which provided a step by step procedure for removing the interior panels and accessing the grommet to the exterior for routing the power and 4-pin trailer connector. The most difficult part was installing the power wire to the battery. Avoiding the muffler path, the drive train (AWD) and getting to the engine compartment required some path decisions. Lexus does have a cable track for some of the distance which I used. I tried to only expose the wire in the front to rear runs, and kept any left to right runs behind the under body shielding to minimize the possibility of ripping the wire out if I run over sticks or branches. All-in-all I think this is a great product. The trailer lights were very bright unlike the trailer harness on my Nissan pickup truck which drives the trailer lights too weak."
