Step-by-Step Guide
Step 1: Locate the Trailer Connector
The first step is to locate the trailer connector on your Ford F550. You can find it under the rear bumper on the driver’s side.
Remove the connector cover to gain access to the wiring. You’ll find the wiring harness tucked away inside a protective covering.
Step 2: Disconnect the Battery
Before you start working with electrical components, it’s always a good idea to disconnect the battery. This will ensure your safety and prevent any damage to the electrical system.
Locate the battery under the hood and disconnect the negative terminal.
Step 3: Remove the Protective Covering
Once you’ve disconnected the battery, it’s time to remove the protective covering that surrounds the wiring harness.
Use a screwdriver to remove any screws or bolts that are holding the covering in place. Then gently peel back the covering to expose the wiring.
