You can download a free 70 Plymouth manual from here. You'll have to "play" with the page numbers as the numbers appearing in your reader will be consecutive, whereas the shop manual uses "dash" page numbering. Not that hard:

I've done this, it just takes time, patience, and effort. Drop the column, pull out the dash cluster, and then pull out the under dash harness. Lay it out on your bench/ old table, etc, and drive nails in at the branches of the harness and fasten it so you can see how it lays out. Then cut the tape/ unwrap, inspect, and repair/ replace as necessary.

This stuff is cheap thermoplastic, so heat welds adjacent wiring together. Be sure and inspect it carefully.

It REALLY would help if you would learn to use proper punctuation so the rest of us can read what you type.
