The driver side harness plug is for the wipers. The other two are engine and forward lighting. I have a detailed video of factory underhood wiring here: http://70duster440.com/downloads.html (See video number 5).

Just about any donor a-body from the era will get you a working plug and harness. The only difference may be in the 2-speed or 3-speed wipers harnesses - which can be modified if necessary. I have an engine compartment diagram here: http://70duster440.com/EngineCompart70.PDF

No problem. If you refer to the diagram you should be able to add the appropriate wires to your harness if they're missing. (It's right at the top of the drawing when it opens). You need wires to run from the NSS though cavities C&D of the bulkhead connector. Again, you can probably scrounge a NSS harness from a donor car. The other two prong female plug may still be on your main harness near the bulkhead connector.
