The Pac board I had in my cab has a 4-pin molex plug wired to the inside edge connector... it appears this molex supplies voltage and ground. I picked up a Pac board from a KLOVIAN assuming this was standard on all boards, but the board I got did not have this 4-pin molex soldered to it.
(A) Is this 4-pin molex connection stock or was it added after the fact?
(B) Would I be wise to add this molex hack to the new boardset even though it appears to be working with just the edge connector alone?
