Can the Transfer Case Switch that supplies power to the Front Axle Actuator be replaced without dropping the Transfer Case and where is said switch located? Also, does AC Delco offer the replacement switch and what is the correct p/n for a 96 K2500 Pickup 8600 GVWR? Rock Auto only lists a Dorman as available, a 2-pin p/n
600506 and a 3-pin p/n 600502
