Classic Update kits are designed for projects that require more circuits than would have been available in an original chassis harness. This harness includes Dash harness connector for the 69+ GM  steering column connector.
The wiring was great and the labeling was extremely handy but I was not impressed with the quality of plastic connectors for the headlights, etc. I really had trouble getting the "female" contacts to stay inside the connectors when pushing in the "male" end. It was designed to be easy but it was really a struggle and added many hours to the process and required manual soldering instead. Other than cheap connections, everything else was complete, thorough and the instructions were pretty good. Nice that they provide options for no matter what you are doing with your truck - full restoration or simply replacing a harness on a "survivor". The price seemed steep at first but when you see what you get and the thought that went behind building it, it's probably worth the value.
great, full, complete and very detailed kit. I researched a lot of kits andI feel that it's the best one on the market. I would buy again and I would recommend it to anyone wanting to update their electrical system, it works great with stock, aftermarket and perforamnce componets.
