Unsure of the correct name for this connector. Ordered one from Classic Industries, but it is for a single wire rather than 2-wires.

70 RR engine harness.

I have that style and many other O/E terminals that I acquired from a "closed" Chrysler dealership. PM me if you're interested.

That is a single female connector specific to the '68-'70 harnesses. May have been used on other years. Aftermarket do not have that ridge, they are smooth. There are two wires connected inside the single female terminal inside. Do you need the connector(plastic piece) or the female spade terminal)brass piece?

Green with red tracer pigtail wire was for a '70 B dual horn. Do you have the single Beep Beep Road Runner horn? Somebody may have changed harnesses before you got the car and you don't have to pigtail wires for a single horn.

Good info. I was actually just using that one as an example. There is another location where the previous owner used a generic female spade connector and I want to replace with the factory style. So I need both the shell and the female spade. The one I bought before only accommodates a single wire and not two wires like the horn connector. I need the two wire.

Ok you'll need a terminal for 12 gauge wire then. You can fit two 16 or18 gauge wires into the crimp. Napa sells the terminals. They were known as Packard 56 way back in the day, lately called GM Spades. As for getting the correct plastic connector, check Totally Auto. They are a sponsor here on Moparts. I've bought used connectors from them.
I had posted about rewiring a '70 B body, listing parts and tools used at the link below. You may find some useful info there.

This is where I bought my terminals. You have to buy in bulk from them though, I think the minimum order is $20.

Here's where I got my dual wire terminals. Don't remember if they have the cover without the little catch ramp though.
