Ok sorry for all the posts, I see my problem now. The aviation cables have mirrored ends the assembly guide, which of course would require the connectors to have mirrored ends as well. Sorry for my confusion!

Oh! I just noticed in your post you said to use a male connector in the electronics enclosure but a female connector in the wiring harness.. this must be it! I did male in both. what is confusing to me is based on the assembly instructions it looks like both the harness and enclosure are using male connectors, not female (I assumed the cable had female on both ends)

Thanks for your reply! regarding the photos, there is text in both descriptions saying it is from the backside, which is why I'm confused.. because stepper online wiring diagram for the motors lists black as A+ (same as electronics enclosure

) But the wiring harness seems to have green hooked up to A+.. unless I'm just super confused ?

I believe that is correct, keep in mind the first picture shows the backside of the male connector in the robot base that uses black green red blue LED strip wire and the second picture is for the robots wiring harness which is the female connector but uses for strand speaker cable that is white black green ed
