This is one of the best deals for the money out there. I got mine from C&L Rod & Custom Parts, cost me $185 for the 21 circuit kit. It comes with connectors, terminals, and decent instructions. I admiut the instructions could be a little more detailed, but if you have a basic understanding of electricity, you can get the job done. I spent a Saturday doing mine, and it worked great never any problems. For the record, I put this kit in my last 57, and would use it again, except that I got another kit for this one...read the next review for it....
