I just purchased an EZ Wiring harness through recommendations on this site. I have a '50 with no bells and whistles and I'm just trying to make it run, so I opted for the 15 circuit kit for $170 ($191 with shipping), and seem to be removing more circuits than I'm keeping. It arrived quickly and I'm in the midst of installing it. So far I'm happy with the quality, but the instructions leave a bit to be desired.
