Cadillac SRX First Generation Forum - 2004 - 2009 Discussion, SRX Trailer Hitch in Cadillac SRX Forums; For those of us interested in trailering, my dealer here in Detroit advised me today that the GM factory hitch ...
Update to my original email.... dealer installed factory hitch and wiring. very nice! I will post pics this weekend. Class II hitch with 1-1/4 box receiver. Electrical plugs right in the existing electrical connectors in the rear. I have install docs also....not dificult, but you need to drop tire and exhausts. Only a slight mod to fascia for clearance at the rear fascia lip, which is not visible.
I would highly recommend getting the factory hitch and wiring. My cost was below list, so I can't advise what your dealer may charge.
Here's a pic of the "official" GM trailer hitch for the SRX. Hitch is P/N 88961322. Wiring Harness is P/N 88963947. You need both. Install instructions are well written and not difficult. You will need to trim the fascia about 2 by 6 along the facsia bottom edge in the middle to make room for the hitch, which is not visible unless you are on the ground looking up. For reference, a 3-1/2 inch drop ball mount with a 2 in ball is 15 inch from the ball tip to the ground.
