Where is the wiring for trailer brake controller on 2014 Silverado?

Here are all your fuses and relays. There is only a relay for the trailer lights. In modern vehicles the turn signals are a function of the body control module.

It is located on the side of the instrument panel, on the passenger side, behind the cover. The location of the fuses in the passenger compartment: Chevrolet ...

If your Prodigy P2 brake controller is flashing 00 and .c, it could indicate an error with the brake controller's connection to the trailer or the brake controller itself. Here are a few things to check:

1. Verify Connection: Check that the brake controller is properly connected to the trailer's electrical system. Make sure the trailer plug is firmly seated in the brake controller and the tow vehicle's connector. Ensure the pins and sockets are clean and free of corrosion.
2. Check Brake Controller Settings: Verify that the brake controller is properly set up for your specific trailer's weight and braking system. Refer to the brake controller manual for the recommended settings.
3. Check Trailer Brakes: Verify that the trailer's braking system is functioning properly. Check the brake drums and shoes for wear and damage, and make sure the brake adjustment is correct.
4. Check Wiring and Fuses: Check all wiring connections between the brake controller and the trailer, as well as the tow vehicle's wiring and fuses. Make sure all wiring connections are tight and secure, and that all fuses are intact.

If you have checked these items and are still experiencing issues, it may be necessary to take your vehicle and trailer to a certified mechanic or dealership for further diagnosis and repair. The hot brake smell from the car brakes could indicate that the trailer brakes are not functioning correctly and that the tow vehicle's brakes are doing most of the work, which can lead to overheating and brake fade.

Hi Donald,
It sounds like a wiring issue. Double the wiring to your connector on the vehicle. Also check the wiring on the trailer connector. I have seen many trailer that are wired to ground through the ******, this of course will cause an intermittent ground and flickering lights. you only need four (4) wires... One for a ground, One for running lights, and Two wires for brake and turn - one wire for the left and one wire for the right. You can also find the proper pin wiring for vehicle and trailer on the internet. Cheers. I hope this helps. John

How have you tested this? If you are just looking for the stop or brake light, you need to test by pressing the break and probing the same pin as the turn signals as the vehicle does not have separate brake and turn signals. However, If the problem is that you have no signal for the electric brakes on your trailer. You must have a brake controller installed. If there is one installed probe the blue wire coming out the back end of it and press the brake to be sure there is brake output. It is possible for a controller to go bad, and not output anymore.
I wrote an imformative article on diagnosing wiring problems. Click here to read.

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 ! ! !

Under the pan on the drivers side u can install the proper harnes for your trailer. The maim post for trailer brakes is on the front fuse panel under the hood.If you are running your own in line trailer lights...........I would start at the main break away dis-connect.

if its set up for trailers with brakes, it should have small black box under the dash above the pedals; if there is one you can adjust the brake timing to syncronize the trailers brakes with the trucks; if there is not one you can purchase one and mount it and run a few wires

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!

I had the same problem with my 2002 Silverado last summer when I first bought my boat and was getting the trailer ready to go. Like an idiot, I rewired the boat trailer on that side before I decided to look at the owner's manual. The pickup has separate fuses for right and left side of trailer. They're located in the big box in the engine compartment. I replaced the 10 or 15 size fuse and haven't had a problem since. Hope this helps!

If the brake conrol iis activating by manually moving the slide lever but not with the depression of the pedel the problem is no brake signal you need to have power to the red wire coming into the brake control. One of the two white wires coming from the brake switch is switched power and you could wire in there. A test light and time will fix your problem.
