Agreed. obviously, your best bet in matching harnesses is to replace with a new JBL stereo, however there are no guarantees they will match. There is a possibility that they sell conversion plug, but not as common as you would think (or as easy to find).
Typically, it is just easier to use crimp connectors and a good crimping tool and connect one at a time. Having both manuals is helpful, otherwise it's a guessing game on the other end. I cut and crimp one wire at a time.
