After researching installation of a hitch and wiring harness for my 2010 Lexus RX 350 I went on the Leonard web-page to order a Curt 13143 class III hitch and a Curt 56083 custom wiring connector; I was very pleased to find out not only did Leonard have both part but they were discounted too, so the price I paid was less than I expected. The parts arrived in 3 days, and installation went very well. Taking my time I was able to install the hitch and wiring harness in 4 hours, and I am very pleased. This is my second purchase from Leonard, though it was my first on-line purchase from Leonard and I couldn't be happier. Thank you.
