Any electrical guru's know off hand what these are for?

What a mess and a fire waiting to happen. Get the factory manual that is specific for the year of your car because it will have the wiring diagrams for both the /6 as well as the V8. Personally I would probably end up buying complete under hood wiring harnesses before it was over.

Here are two manuals for your 73 that you can download for free. You will find them to be one of your best friends.


1973 Dodge Body Service Manual

1973 Dodge Chassis Service Manual
