Not complaining- just confused. If after buying this, I still need "RCA connectors, a serial connector, a bunch of wire, some sort of multi-pin quick disconnects, and soldering ability", what exactly am I paying $65 for? Thanks.

Perhaps we don't remember what Empeg Ltd commanded for a sled with a pre-wired connector. I recall it being in the $129 neighborhood.

I can't afford to pay someone to wire-up 50 wire harnesses and I don't have the time to do it myself. So, for $65 + $12 for odd-ball connectors you gotta do it yourself... or hire some day workers to do it for you.
