Ok bought wife an 03 blazer well July 16 2002 mfd, so anyway on to the fun. To date have upgraded door latches, door wiring as the latches that came w the truck were two connector, w three connectors latches (better power door locks,and one odd plug in I havent quite figured out what it does yet, thin orange wire and black wire, central locking??) Pass side is the updated wiring side so far I have been really busy w this truck and after 2.5 hrs repairing drivers door panel as it was 3 parts when I got it. So not in a red hot hurry to tackle the door again. After having to do some engineering on pull handle (typical pull handle screw hole blow outs) added fog lights also using OEM stuff, was plug and play less signal fixtures, and bulbs. Wheel controls also OEM stuff was plug and play less double din radio w wheel control compatibility. Power seats are next wiring is also supported. Shooting for SLE package all said and done. What is everyone else putting together?
