I'd do it just for the $20 since you're interested in seeing what all is involved to convert to PL and PW. I can tell you, you'll have to get antoher main harness from a Silverado out of the junk yard. It's the one that will go from your fuse box to the under the dash with 2 plug-ins, one goes to the left door, one goes to the right door. Then the harnesses off your doors are routed thru the kick panel behind the glove box and under the instrument cluster, to this main harness that goes to the fuse block. A bit of a hassle, but it can be done. I'd suggest going to a Pull a Part type lot and pull one apart, then you'll KNOW what to expect and how to route the hanresses, but it should be all plug in and fairly easy to do. You'll have to pull your fuse block off the firewall to plug into the back of it though.
