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)

If your vehicle came from the chassis factory with a Telma installed you have an OEM installation, and will need to reference the OEM wiring diagrams: Mack, Autocar, Peterbilt

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.
