Wiring Diagrams

To locate the correct wiring diagram for your vehicle you will need:

  • Make and Model of ABS ECU
  • Location of ABS ECU (Cab, Frame/Chassis)
  • Make and Model of Transmission ECU
  • Control type (Foot, Hand, or Off Throttle)
  • Type of Brakes (Air, Hydraulic)

 Universal Wiring Diagrams may not have the Make and Model of the Chassis referenced, only the ABS ECU and Trans ECU, which is what the Telma connects to.
