I've made some of the smaller pieces (like the convertible top harness) but finding all the right connectors is impossible (especially the ones on the dash harness.) The metal terminals aren't that hard to get, but the plastic housings... And like the guys said, you'll never find the same wire colors (i.e. purple with a pink tracer...) so you would have to substitute a lot of them. I can give you some sources if you want to try.
