Question about Chevrolet Silverado 2500HD

1 Answer

Location of Brake Pressure Sensor on 2009 2500HD Chev Silverado. This is what tells the factory Integrated Trailer Brake Controller how much you are applying the vehicle brakes.

My master cylinder only has a sensor in the plastic brake fluid reservoir.

GM also offers a built-in trailer-brake controller on 2009 half-ton trucks. Like Ford's, when activated, the truck's ABS brakes reduce gain to the trailer brakes. In GM trucks, however, the controller gain adjustment and hand control are on the left side of the steering column. It's all electronic, not hydraulic, This link has an article you may find interesting Trailer Brake Controllers What Wrong and What Right PickupTrucks com News

I have a seven plug for my trailer on the back of my silverado. what do i need to do to hookup my elect brakes on my trailer to the truck


Do you already have a factory installed brake controller, or are you installing an aftermarket brake controller? Also, take time to check owners manual in fuse section for possible circuit already in fuse/power distribution box (under hood) and would require you to just insert recommended fuse.

2009 Silverado 4x4 pickup with towing package and factory installed Trailer Brake controler installed at factory. The system has worked in past. I had my Stock trailer rewired and things tested out fine...


It sounds like you lost a ground.
check traier hookup first.
Probably not the controller.
P.S. There are multiple fuses for this setup. check all ! ! !

Were do you hook up the two wires under the hood for trailer brakes on a 2000 silverado


Sometime around 2000, GM started putting trailering pre-wire harnesses in the vehicle. Your truck may have this harness built in and would greatly simplify brake controller installation. Look under the glovebox and see if there is a wire harness tied off. There will be four wires in this harness, which should be run over to the steering column to use it. Most trailer brake controllers are compatible with this harness.
The four wires in the harness are: Red, 12vdc; black, ground; blue or purple, brake pedal; and brown or white, trailer brake wire to seven pin, four pin, or five pin connector at trailer hitch, if your truck came from the factory with a trailer hitch.
If you are adding the hitch and do not have the four wire harness, the under hood wires from your brake controller are Red, connect to one of the studs under the distribution box cover (the distribution box is on the driver's side against the firewall. Underneath the cover are two large threaded studs which are hot from the battery all the time); and the other wire from your brake controller would have to be run the length of the truck along the frame, tied off in several places, to the trailer hitch connector on the bumper. Follow the directions that came with trailer hitch wiring connector to connect this wire to the proper pin in the connector.
If this has helped you, great, and please remember to vote/comment.
Good luck!

Hooked my 2007 Sprinter camping trailer to the factory lights/brakes hook-up located below bumper of my 2005 Silverado 4x4 extended cab truck. Everything works fine except for the right trailer turn...


Is this a 4 way or 6 way connection system? If your truck is wrong, then all factory equipped trailer package harnesses would be wrong, tell your trailer guy...I don't think so.
Is this the first trailer you have hauled?
Let me know, and we will go from there.

Integrated brake controller will not recognize a electric over hydraulic brake equipped trailer. why?


The GM Integrated Brake Controller seems to be a real problem when it comes to electric ove rhydraulic actuators (what were their engineers thinking?). I have talked with representatives from Carlisle (which is incompatible with a half dozen or so controllers by their count) and Dexter (whose ONLY incompatibility seems to be the GM controller). I have been told there is no solution to the incompatibility for those 2 actuators. I just got off the phone with the Titan Tire Corporation tech support (1-800-832-8781). I was given a couple of part numbers for adapters they claim will allow the GM integrated controller to work with their Electro/Hydraulic actuator. I have not tried their product with the company's '08 Chevy Silverado, I'm just passing on what I was told. There may be other manufacturers of actuators I haven't found yet, so there may be a better solution (other than GM using a little forethought with their designs!).
