Another update!
I sent the photo of the pickup wiring to Sterling and they said that it was wired correctly (at least for this bass's electronics as then intend them to function).
I got the new wiring harness (all the pots, the switch and the input jack) today in the mail and will get it wired in with the stock pickup in the next few days hopefully and will post the results here.
Also, I have read mostly negative things about the Sterling customer service and I have to say, my experience with them has been spectacular! I bought this bass used, so they technically don't have to offer me any support really, and they have been very responsive and even sent me the replacement electronics for free. Very impressed!
