I have some info for the late model nose swap: The harness for the at least 88 model only needed the 3 wires for the front marker/turn signals spliced in. You do have to dig into the late style harness a little ways until you find the wiring "junction" from the factory, and then cut it BELOW the soldered splice. Now jsut splice it into your original harness, after you verify the correct wiring connection BEFORE you crimp/solder. Oh, and don't forget to cap off the extra "hot" wire on each side that you will end up with. Look at the "pass.side" pic, and you can see what I mean.

 

 

 

Other than this, it was pretty much a "bolt on" over a couple of hours. :thumbsup:
