I bought one of their Classic update wiring kits. This is a top notch #1 product they sell. It comes with all of the factory plugs for the heater, light switch etc. The fuse box fits in the original factory hole. It has all of the wiring for upgrades for fuel injection, elec speedo and all your power accessories. It also has a pigtail to hook your fuel pumps etc to so you don't have to splice anything. The instructions were excellent and the few questions I had their free tech line answered correctly and promptly when I talked to them. I would recommend this product to anyone looking to rewire their car.
