12–Volt Terminal Board Connections

Remove the upper dash to access the 12-volt terminal board 1. Always make sure that all 12-volt electrical accessories are grounded directly to the negative (-) post on the terminal board. Never use the chassis or body as a ground connection. Use the positive (+) terminal only for accessories that require constant power (when the ignition key is off). Use the accessory (ACC) terminal for accessories that require power only when the ignition key is on.
