Depends on what you're end goal is. If you're doing a restoration then your have to go with the reproduction harnesses - end of story. But if you're building something non-stock then you have a choice of the aftermarket kits. Personally I don't see much difference between them other than some ridiculous prices. Each have options of number of fuses. ALL of them have labelled wires. Some offer a "dash" kit which is nice since that should be completely wired separately. I have a kit from Kwik Wire - which I bought at a show after a lengthy discussion with the man who makes them .
