Yeah, that basically looks the same as the other photo I posted, just chop off the round female motorola plug.
I don't believe you would need to follow the antenna cable all the way to the antenna, unless you somehow really lost the wire in your dash lol. If the wires are still attached to the connector, then you'll pretty much have a great idea of which wire is which to connect. I haven't personally done an antenna cable repair hands-on (I was preparing to fix a friend's antenna in a 92 civic) but here is the video i used:
So basically the actual antenna should be co-axial/shielded type (basically having two wires: one for signal and one for antenna ground), and then the blue wire is for the antenna amplifier. If you strip the black antenna cable, you should have some wires exposed, and then another insulated wire in the core. So, in total, for this repair, you should be making three wire connections.
In my opinion, it's up to you if you wanted to solder. Crimp connection will work also
