Need some help - got a 2004 V8 SRX which did not have the towing package; I purchased a Draw-Tite factory-style hitch for about $140 and installed it (not for the faint of heart - I have a hobby lift in my garage or else I would not have tried this - took 5 hours and brute force thanks in part to lousy instructions) but now I need the wiring kit. I would prefer not to go to the dealer if there is an aftermarket source out there that has a simple plug-in adapter (no wires to splice). Can't find a wiring kit that doesn't require splicing - any ideas?
