Important
Installation of an electric brake controller and the wiring connections outlined in this bulletin are the responsibility of the dealership or
customer. These repairs should never be charged to warranty. If you have any questions, please consult with your District Service Manager.
Some customers may request to have an aftermarket trailer brake controller added to their vehicle, OR in lieu of the factory integrated trailer brake
controller (ITBC) (RPO JL1).
Installation Instructions
Starting with the new 2007 full-size utilities and pickups and 2008 HUMMER H2, there is no longer an electric trailer brake controller pigtail harness.
To install an aftermarket trailer brake controller, use the four blunt cut wires located near the data link connector.
The following steps should be used to complete the installation.
Important
Ensure that the ringlets are not interfering with the UBEC cover.
1. Place the terminal on the larger of the two studs at the front of the electrical center and secure with an M8 nut. This is circuit #242 to stud #2, to
power the aftermarket trailer brake controller.
Important
The fuse is already present in the vehicle to power the electrical trailer brake controller system.
2. ONLY For Vehicles Equipped with JL1 - Locate connector X126 or X115 (varies with vehicle build; refer to SI) near the underhood fuse block.
Refer to SI Document ID# 1849049 - I/P Harness-Engine Compartment. Circuit 47 from the blunt cut wires near the data link connector will end
