Not to bring up an old thread, but I just purchased the $150 classic parts harness for my 54' w/ alternator. I have very little electrical knowledge, other than having installed a few sockets in the house, and some speakers/amps in an old car I had in highschool.
It took me a little while to get the harness oriented... I laid it out in the truck bed before trying to install it so I could get my bearings. Easiest thing for me to do, was pull out the headlight switch, and get that connected to the harness before anything... allows you to really see where the wires might be going for the rest of the truck.
Quality looks good, and I have only found any faults with it (which for those with more electrical experience it wouldn't be a problem). IF you're using a turn signal switch (such as the 7-wire from classicparts), you have to wire in your own flasher unit and fuse... but really that isn't all that terrible.
I'll be continuing to remove old wires, and install the new over the next week or so (hopefully I'll have time).
