Hello All, New to this forum, but not new to chevy trucks, have had many. Need information on my new 2008 2500 hd. All past trucks had dedicated wires for hooking the third brake light or high brake light on truck caps. They were always not far from the 7 pin harness. Have they done away with this on the 2008 model year. Boy have I searched for this wire can't find it. Any help would be appreciated thanks, Ridgebury

 

pretty sure they have done several hitch and harness combos and havent seen that wire on them
