Possibly the ESOF computer/brain
The wires go through whats called the BWP, or the big white plug
this was used 89-94 on these trucks as the wiring through firewall connector.
The short is usually inside a component like the esof computer or right at the back of the fuse panel
dead short can be really fun to find under there! Easiest way to start is just unplug things on that circuit until the fuse no longer blows, sometimes you win and the culprit shows itself right away!
