started working on the harness some more, basically took all the switches out of the dash cluster and sent the rest to instrument specialties for re-lettering, circuit boards, and calibration. cleaned up all the switches with contact cleaner, lubed the mechanical moving parts, was planning on replacing the chrome covers, but with the buffing wheel all turned out great except for wiper switch, probably overheated and caused chrome to peal. Plugged all those in to test, minus wiper, most of this kit is plug and play, basically figuring out what you want on your car, has all the electric fan, electric choke, tac, extra courtesy light receivers for under dash, all plug ins for door jamb switches map light, glove box light ash tray light, third brake light, etc. even has the four speed back up warning light in dash. I think they offer more original wiring kits if you don't plan on upgrading items. the end wires on the far connections like the headlight harness, taillight starter wires are extra long for a custom fit, that's where the crimpers come into play. the steering column harness needs to be taken apart on the column feed connector, (that is not part of the new harness) and change it out to there style, same on wiper plug in under hood. haven't found out why there different yet but will be into that soon. hi beam switch is different than one for a 68, it has three flat prong parallel to each other instead of having the single one turned 90 degrees. basically if you can read a wiring schematic, and know how the car works, i think most can do this. I've been using a little dielectric grease on the connections just to ease the plug assembly they are tight and right, just how ya like them!
