The High Beam Relay is located in the PDC under the hood, and it controls the high beam headlights. The Low Beam Relay is located in the Totally Integrated Power Module (TIPM) under the hood, and it controls the low beam headlights.

Fuses

Fuses are designed to protect electrical systems from voltage spikes and shorts. In the 2012 Dodge Ram 1500 headlight wiring diagram, there are several fuses that are used to protect the headlight system.

The 20-amp fuse that’s connected to the headlight switch is just one example. There are also 10-amp fuses that protect the High Beam and Low Beam Relays, as well as a 15-amp fuse that protects the TIPM.

Wiring Harnesses

The wiring harnesses in the 2012 Dodge Ram 1500 headlight system are designed to deliver power to the appropriate headlights. There are two main harnesses: one for the high beam headlights and one for the low beam headlights.

The wiring diagram will show you how these harnesses are connected to the relays, fuses, and headlight switch.
