Maybe - in a roundabout way.
Anyway fuses for ABS are #14 (60A) under hood, and #15 and #15 (both 5A) under the dash. ABS light fuse is #19 (10A) under dash, but that one should be good if the ABS light is on.
ABS is connected to the GEM and instrument panel in various ways, including the brake fluid level switch (is that OK?), and the speedo signal.
The turn signal flasher circuit and the abs fuse #25 are both powered thru the same contact in the ignition switch (one of 4), but that circuit and the one that actually runs the truck are powered by the same fuse, so that might narrow it down to the ignition switch itself. That contact (hot in run) also powers the air bag circuits, heater controls, and trailer battery charge relay control circuit. Check to make sure those are powered with the key on (be careful of messing with air bag circuits though). The output terminal from the switch is "A4" (should be a grey/yellow wire)
