I recently installed a trailer hitch on my 2006 9-5 wagon and am now looking to install the wiring for some trailer lights. I've read the posts about the older 9-5's having the wiring harness in the rear hatch area, however, because mine is a later model, it didn't come with the 10 pin connector. I'm wondering if anyone has any information on the wiring for these models. I'm nervous that splicing the tail light wires to install a typical wiring kit will cause rear light error messages on the SID or that my parking sensors will constantly beep if there is a trailer behind me. Any help is appreciated.
