Where do these connectors go?

Yes. But if you don't have the body manual, download that from there as well. There is some wiring shown in the body manual as well

In the chassis manual, get into the schematics area and read all through that. My page no's may not be the same, but some examples. The Dart stuff starts page 8-152, "Locating a system or component"

On 8-164, after the diagrams, are depictions of the connectors, with their wire colors, how they are shaped, and approx. locations. Note that in the diagrams, every depiction of a connector point, which is not the entire connector, MAY only be a SINGLE terminal of one, there is an oval with a designation.

Just an example, the last page up, 8-183, at the bottom of that drawing, is 3 ovals, such as CI-5. "CI" means "connector, instrument panel,", where something like "CE" means "Connector, Engine Bay". So if you look down on 8-164 and onwards, and find "CI-5", you'll see that "E-2" series of wiring was Orange, involved with the steering column connector for the ignition switch, and so on.

These diagrams can in some was be a PITA. You can also download aftermarket ones over at MyMopar, but they are not as complete and leave out some details and options. I use both.
