You bet. I am not actually sure what it came from. I cut a few harnesses like this from the jy this past spring as I was making a modular adapter to add a relay into the circuit so needed a good male/female setup to reverse. So it was just going around finding connectors that looked good to dissect and find the best one when back home.
Sounds like you've got a good plan.
