i have that same rattle you had in the rattle when cold thread. You described it to a tee. i cant find it and the dealer couldnt find it either. Was the wire harness clip on the motor side or behind the dash? i have a 13 tss. Please help it would be greatly appreciated. Maybe take a pic of the clip and send it to me or explain exactly where it is located? My email is maynardjk@me.com or text me 314-606-0827.
