Dunk did this. At best, you're going to knock no more than 20 lbs out of the car though. I question whether it's worth the effort. I have a WRX harness sitting in a box. I've carted it around. No more than 40lbs for the whole thing including all the little control boxes for DRL, Power locks and the like. The hassle factor is high and the chance of cutting the wrong wire is very high because subaru uses the same color codes for multiple circuits.
