Okay, 2003 5.3 engine/harness/PCM, I'm getting close to finishing the wiring up, but have run into an issue. Circuit 806, a purple wire that goes from the crank fuse (Pin F3, COnnector 2, UHJB) to pin 59 on C2 at the computer. Does this need to be hooked up? I'm using the starter solenoid wire from the car's harness, so can't tell if this wire needs to be hooked up or not. Anyone know for sure?

 

I know on a 2005 the crank wire was not needed to make it run...
