Hey,
Found a starting point for you. I typed in JST dual row into google and got a link to a company in china that sells em.

now, you need a set of calipers off of Amazon(if you dont already own a set.) you need to measure across the pins horizontally, from pin to pin. That spacing is the "pitch" so to speak.

the company also sells 2.0mm pitch connectors on the same site.

Make sure to count however many pins wide, and then the pitch is the spacing center to center. you can also find cables to replace the factory harness this way. hope this helps.
