The Western 29070-1 module acts as the central hub for your snowplow’s lighting system. Specifically, this genuine 3-port isolation module integrates your plow’s electrical functions with your vehicle’s wiring. It manages the headlights, turn signals, and parking lights for both 2-plug and 3-plug systems. Additionally, this “Green Label” module handles both DRL (Daytime Running Light) and non-DRL vehicles.
Initially, you will find the Western 29070-1 mounted under the truck’s hood. It protects your vehicle’s sensitive electrical system from feedback or shorts. Furthermore, this module automatically transfers signals to the plow when connected. Consequently, it ensures safe illumination during heavy snow conditions.
Always refer to your Western Plow’s documentation and vehicle-specific wiring guides to confirm compatibility and proper installation procedures.
Compatibility and Diagnostics
Moreover, ensure your 35500 handheld controller functions correctly before you replace the module. Use the following table to verify your system requirements.
| Part Number | Item Name | Diagnostic Role |
| 29070-1 | 3-Port Module | Primary lighting gatekeeper. |
| 28587 | Control Harness | The 4-pin data line. |
| 26357 | Headlight Adapter | Connects module to truck. |
Finally, always use dielectric grease on all ports. This prevents moisture from corroding the internal pins of your 29070-1 and 28587 connectors.
