Regardless of how they define the harnesses, it is all one harness. The different harnesses, in my opinion, are merely an easier means to identify locations of components. I've seen no easy way to seperate any of the three harnesses I have. But since you asked, it is the front wiring harness. It is located right next to the RH headlight, the RH turn signal, the RH abs sensor, RH side market, and RH radiator fan.
It has ~30 pins, but its not the easiest to count. I have just spent the last 15 minutes tracing wires, counting pins etc and I have it 100% confirmed that this is the ABS Control Module connector, id B301. The main ABS power wire traces from the connector to fuse #8 in the main fuse box.
