Want to control it?
Disabling or turning ECS & TCS off and on:
F26 (30 amp - Antilock Brakes - Stability Control Module - Valves) is the fuse to pull.
Or
Complete this mod to turn it off and on, on the fly in any mode, 2wd, 4wd auto, 4wd or 4wd low:
Wire in a 30amp fuse from F26 socket * to a 30amp NC (normally closed) relay.
Wire in a dash on/off switch to control the relay. Or, I used a remote-controlled wireless switch to control the relay and linked it to a HomeLink (garage door) button. This saves the trouble of pulling wires into the cab and installing a switch.
You know when it is off because the EVIC displays "Service ESC" and "Service ABS"
* I modified a 30amp fuse by cutting the top off, cutting the bridge wire and wired to the
relay via the new inline fuse. Be sure of what side of the F26 socket is 12v
I modified the fuse because I could not find an adapter to fit the F26 Fuse Socket

F76 fuse (10 amp - Antilock Brakes - Electronic Stability Control) - DO NOT PULL THIS ONE! EVIC displays "Service ESC" and yellow engine (MIL) light.
F06 fuse (40 amp - Antilock Brakes - Electronic Stability Control Pump) - DO NOT PULL THIS ONE. Leaves error codes that have to be cleared.
