Yesterday I installed a 6 gauge white faced Stewart Werner setup I bought from Tom. It looks awesome, probably my favorite upgrade piece. It took me about 5 and a half hours, but I wasn't in a big rush and read every step over and over again until I was absolutely certain to what I was doing. My only real difficulty that I encounterd was unplugging a small 6 wire plug that came off of the stock cluster. The plug was a little different than described and was a real pain to disconnect, let alone get to. I had to remove the stereo and loosen up the environmental controls to get my hands up behind there to release the barbs holding the plug in place. Overall the installation was easy, just time consuming. My GN is getting a whole slew of performance upgrades thrown on it and I really didn't want A-pillar or console gauges in the car, the GNX style dash looks so much better than having those IMO. I'm really happy with this buy and highly recommend it.
