1996 Plymouth Voyager replaced drivers side front door with

Electric window would not work due to broken cog.
This was an after market installation. I bought the
car used. It was cheaper to buy another door than
to try to repair the old one. I bought a 1998 used
door. Needless to say the wiring harness from the
1998 will not match up to the after market installation
harness on my 1996. Any help on making these
compatable?
