Having an accurate wiring diagram for your 1972 Cutlass Supreme is essential for completing any restoration project.

Fortunately, we’re here to help.

To properly restore your 1972 Cutlass Supreme, you'll need the right wiring diagram. Wiring diagrams provide the layout and connections of the electrical system in your vehicle.

Once you’ve found the correct wiring diagram for your Cutlass Supreme, there are a few things you should know about what it contains. First, the wiring diagram will list the order and location for all of the components, including the switches, relays and connectors.
