I just wired mine to the 4-pin seeing as the 3rd gens have theirs hanging under the bumper and I only use my 7-pin for towing anyway.. I had to wire in a new 4-pin because the old was corroded and caused the left side to be duller and no left blinker at first.. Works great now.
And ya he paid.. He did a hit and run but neighbours saw it and told me when I came out after he took off and got hold of him through his mom and he admitted and said he freaked out and took off and would pay cash. He scratched my plasti dipp and where he hit already had a dent in my steel bumper and a scuff beside the tail so it made it look worst.. He had $2500 worth of damage to his car from my bumper.. He didn't want to go through insurance so I had him at mercy lmao.. Ended up getting $500 for 2 new tails because mine were tinted and cant match and for "body damage"... So got used tails for $80, tinting supplies and tow mirrors
... Don't try a hit and run on me..:P
