The best quality as far as completeness and parts, is American AutoWire. Also the most expensive. The actual wire is the same as all the others. I was very pleased with their Classic TF harness after I got over the price. Great Packard56 connectors and terminals. All the lamp sockets and wiring. Nice colored diagrams to match the wire colors. Provisions for every possible add on accessory. Nice fuse panel. After you factor in all the switches and extras you get and you don't get with the others, the price becomes understandable.
