It's one of the few, and I mean few, reproduction parts that fits and functions very well. I have installed countless number of these in all sorts of cars and never a single issue. Even the dash harnesses are great. I have "restored" several sets of original harnesses as well. Lacquer thinner works great to restore the color of the wiring and have the proper harness wrap and most original connectors. With patience, one can get a a nice finished product. But unless you are looking for the ultimate in correctness it's still better, from a functionality standpoint, to have the new stuff. You would be shocked(pun intended) at how much resistance an old set of wires carry.
