2005 F-250-550 Aftermarket Trailer Brake Controller Connector
Models Affected 2005 F-250-550 trucks not equipped with Ford's Trailer Brake Controller (Option Code
52B)
Purpose
To locate the connector for Aftermarket Trailer Brake Controller installation.
Description
An aftermarket trailer brake controller (ATBC) will need to be installed if Ford's Trailer Brake Controller was not
ordered and/or a trailer utilizing electric over hydraulic brake or disc brakes is being towed.
A pigtail (part no. 5C3T-15A416-AC) may be provided in the glove compartment (option dependent), which is
intended for use with an ATBC. The documentation accompanying the ATBC pigtail (see Photo 1) was incorrectly
released and describes the location of the connector on 2004 F250-550 trucks. Disregard this documentation. The
procedure to locate the ATBC connector is as follows:
1.
2.
3.
4.
Remove the front bezel from the Instrument Panel. Do not disconnect any of the wires.
Raise the bezel to the maximum height allowed by the connecting wires.
Look into the opening created by the raising of the bezel.
Locate the forward (toward the front of the vehicle) section of the "pocket" (see Photo 2) where Ford's
trailer brake controller is installed. You will see two molded connectors with two harness connectors
attached.
5. Locate the four wire harness connector (see Photo 3). The other connector has ten wires.
6. Remove the four wire harness connector from the molded in connector.
This four wire connector is the ATBC connector. Attach the ATBC pigtail to the ATBC connector and install your
ATBC. The following is a list of the ATBC connector and ATBC pigtail circuits:
