hi everyone,
i'm new here. i currently have a curt classIII hitch to be installed on my 04 rx330. i would like to install the wiring. i found this http://www.autoanything.com/towing/75A3875A0A0.aspx and i'm wondering if this will work. otherwise, i think i need to do some splicing or do i need the wires from lexus. can anyone help me figure this out?
