I have a 91 Accord and just had to switch out the door lock mechanism because it of course jammed and door wouldnt open on driver side. Well with that changed out my power locks no longer work (by switch or remote for alarm) everything else works (windows and mirrors) i have noticed the wiring harness is different. The original one has 4 pins and the replacement one has 3 pin. Is that reason locks dont work and if so what can i do to splice in the old clip

 

Did you check your fuse for the locks?
