So, I've got my new old stock AT case and as I was preparing to connect all the 2- and 3-pin cables to the motherboard, I realized that none of them were actually labeled (and I don't have a manual). The mobo (an Intel Advanced/ZP "Zappa") has labels next to the pins, but their arrangement and the way pins are missing are just bewildering.
The mobo came with the CPU installed, and I just removed the fan for the pictures. Its connector (not pictured) was on the rightmost two pins on the FAN header. The speaker cable (also not pictured, it's not integrated into the case) is obvious, with just two possible ways of attaching it. The case doesn't have a keylock, so that'll probably be left empty.
But other than that, I don't know what goes where, and I wouldn't want to blindly try all possible permutations, just in case this could end up damaging something.
- Is there supposed to be some kind of standard coloring here that I couldn't find? If not, do I just have to guess what goes where?
- Do I orient all the cables so that the arrow on the connector is nearest to the no. 1 pin on the header?
- What on earth is that one 2-pin black/red cable that comes from the PSU? I couldn't find any references to it.
I used to build a bunch of PCs back in the day, but I guess they were all in the ATX era, where this got somewhat simpler.
