So this pic has a back story....my father in law decided after I had refinished a pair of standard manual door panels for his originally plain jane optioned 77 GMC that he wanted to have power windows and locks after seeing my various express down/up installs on other trucks-so I said fine....I'll build an 81-up style harness for use with your 1977 fuse panel, I'll add a few more circuits and you just need to source nice power doors.....easy right?

Well, he picked up some rust free 1991 Suburban doors and now he wants to add power mirrors! So after already routing the window/lock harness, I needed to add a mirror harness seperate-(usually I integrate all 3 options into a single harness run) but for those of you who may like to add power mirrors to your truck and don't need a new window/lock harness, you can simply drill a 7/8" hole directly above the factory grommet for the window/lock door harness and run the mirror harness out through there and into the door boot.
