Douglas Dynamics 3-port Isolation Module

Technical Specifications Part Number: 29760-1 (Superseded by Part # 29760-2). System Compatibility: Designed for use with 3-plug snowplow systems on newer trucks (including your 2014/2016 Ford Super Duty). Key Feature (Soft Start): Prevents the vehicle's computer from detecting a "short circuit" during light transfer. It reduces the initial "amp draw" or cold filament current inrush, protecting the truck's lighting system from shutting down. Electrical Specs: Fuse Size: Requires a 10-Amp Mini Fuse for Park/Turn and Control circuits. Power Input: Receives a switched 12V auxiliary power input on Port C, Pin C to activate the internal relay. Dimensions: Approximately 7 x 7 x 2 inches and weighs about 1.0 lb. Installation & Troubleshooting Tips Mounting: It is typically secured inside the engine compartment (e.g., inside the driver-side fender) using cable ties or reclosable fastener strips. Handset Power: For the module to provide power to your plow's handheld controller, the headlights must be plugged in to complete the ground circuit loop. Common Issue: If your lower headlights do not turn off when you switch to the plow, it often indicates a reversed plug configuration on the harness (e.g., the black and gray plugs are swapped). Replacement Note: If you need a new one, the current version is 29760-2, which is a direct replacement for your 29760-1. SnowplowsPlus SnowplowsPlus +4 Since you are dealing with airbag issues, note that this module is strictly for snowplow lighting and does not interface with your truck's SRS (Safety Restraint System).
