Please Help Identify wires on harness - 68 Barracuda

You can probably figure most of it out just by starting to put it together. Plug in the obvious things based on connector shape and proximity. Then, based on wire length, there's only so many places everything else can go. Then, as 67Dart has said in EVERY post he has ever replied to, look at the free diagrams available. There wont be that many things left. If you have 1 or 2 oddballs, post a close-up photo here with a description of what side its on, what its near, etc. and someone will then have an answer.
As an example, IF 1 is dimmer switch, 2 would probably be the connector that goes to rear of car (for taillights, dome light etc.) (see if that plug fits), it sure aint gonna fit the radio, the headlight or wiper switch etc. It can all be narrowed down real quick like that.
