Hello, my first post here, doubtless won't be last. I would like to add a 4 wire harness to my 2002 s60. The newer models seem to use an integrated harness connection and control module, which is slick, but I don't see a similar part listed for my generation.

My assumption is that I would use a powered system and tap into the existing light wires in the trunk. Is there a trailer connection buried in there somewhere? I need to grab power so I'm assuming I just use the battery, since it's right there.

 

see if there's anything on volvowiringdiagrams.com I'd suspect there is a harness connection point somewhere. You may also want to use the diagrams on the dealer parts web sites or google for "Volvo 8633880"
