• Where Is Brake Controller Install Harness for 2001 Chevy Silverado 3500
  While it looks like you are pretty close to finding the correct port for installing a brake controller in your 2001 Chevy Silverado I attached a picture of where the install harness does plug in using a harness like the part # 3025-P. For a brake controller I would recommend the Prodigy P3 Brake Controller part # 90195. This is our best selling brake controller because of how well it works and how easy it is to setup.

• Can Factory Brake Controller of 2007 GMC Sierra 2500HD be Bypassed without Dash Codes

It's basically a few wiring connections that need to be made under the dash...

• Brake Controller Installation on a 1999 Chevy C3500 Pickup Truck
  On a 1999 Chevy C3500 there will NOT be a brake controller port to plug in a brake controller. The brake controller has to be hardwired into the truck. Chevy did not start putting in a port until they switched the trucks from C or K to Silverado. Prior to that Silverado was just a trim option. I have included a link to a video that will help. It shows installation on a 1996 C/K series truck. Installation will be basically identical on your 1999 model. If your truck already has a 7-Way...

• Installing an Electric Trailer Brake Controller on a 2001 Chevy Silverado
  On the 2001 Chevy Silverado, there should be a port, located in the electrical junction box on the driver side to the left of the brake pedal. Inside, you will need the port second from the left on the top row. You would use brake controller wiring harness # 3025-P. One end plugs into the Tekonsha Prodigy P2, # 90885, and the other end plugs into that port. There may also be some connections that will need to be made to make the brake controller and 7-Way trailer connector fully functional....

• Brake Controller Not Working with Brake Pedal on a 2004 Chevy Silverado 2500
  On your 2004 Chevy Silverado 2500 you will need to make sure that the red wire in the connector, # 3015-P, is in the correct place. If you are not using harness # 3015-P then that could be the problem. Make sure the end of your harness that plugs into the truck matches the picture I have included. You can also check the stop light and CHMSL fuses. A blown fuse can cause this issue. I have also included a link to a help article that could help because there are some under hood connections...

• How to Determine if a 2002 Chevy Silverado 2500 HD has Factory Installed 7-Way Wiring
  On your 2002 Chevy Silverado 2500 HD, you will need to look above the spare tire for a round plug with a cap on it. I have included a picture below that shows what the plug looks like. If your truck has this plug, then it has the wiring for a 7-Way. To add a 7-Way trailer connector at the rear of the truck, you can use Pollak Replacement 7-Pole, RV-Style Trailer Connector Socket - Vehicle End, # PK11893. The factory harness from under the spare tire will plug into the back of this connector....

• Installing a Brake Controller on a 2000 Chevy Silverado
  There are some connections under the hood that will need to be made to complete the installation of the Tekonsha P2 Brake Controller # 90885 with Wiring Harness, # 3025-P. Once you have plugged in the # 3025-P harness into the port to the left of the brake pedal, you can make the connections under the hood. Locate the power distribution box. There will be a bracket on the driver side near the windshield that will need to be removed. Remove the bracket and power distribution box cover....

The linked article illustrates the process of wiring in a EOH-compatible controller like the Prodigy P3 # 90195. If you follow these instructions you will disable the OEM controller and this change will not generate any trailer brake display messages on the driver information center. The article includes photos and a wiring guide. You...

• Troubleshooting Open Ground Error Code for Brake Controller Install
  The "open ground" error code of a brake controller indicates that the controller is losing the ground connection to the vehicle battery which is the white wire. I'd double check you have the # 3025-P seated totally in the junction box as well as make sure there's not damage to the connector or the pins of it. Also check for corrosion and fix as needed. As far as tracking down the ground circuit on the truck wiring that might be challenging. An easier solution would be to run a jumper wire...

  You can install any brake controller on your 2000 Suburban, with factory 7-way connector, by using the Universal Brake Control Wiring Adapter 1999-02 Chevrolet, GMC, Cadillac, item # 3025-S.

• Installing a Brake Controller on a 2001 GMC Sierra 1500 with Factory 7-Way Trailer Connector
  Since your 2001 GMC Sierra came with a factory installed 7-way trailer connector, GM should have already completed the connections under the hood at the fuse box. However, we have found that GM did not complete the wiring on all trucks, even if they came with the factory trailer wiring. If you plug in your brake controller using a plug-in style wiring harness, like part # 3025-P for Tekonsha brake controllers, and the brake controller does not power on, then the wiring under the hood...

• Brake Controller and Wiring Adapter for a 2002 Chevy Suburban
  Although your friends Suburban might be equipped with the factory tow package, the package did not include a brake controller like it sometimes does in later models. A controller will need to be installed. Not to worry, though. Installing a controller will be simple. If he does not already have a controller, I would recommend the Tekonsha Prodigy P2, part # 90885. The wiring adapter, part # 3025-P will also be needed.

• Troubleshooting Trailer Brake Wiring Issues on a 2002 Chevy Silverado
  Thank you for being very detailed with your question! The first step I would take is to make sure everything on the truck and trailer is wired properly. Your Prodigy brake controller should have the wiring adapter # 3025-P which is custom for your 2002 Chevy Silverado. I recommend verifying you have the correct adapter because # 3015-P will also fit but it was pinned differently for the 2003-2006 Chevy Silverado's. The next thing I would check is the wiring for the 7-way connector...

• No Power on Brake Controller Red Wire
  What is the year, make, and model of the vehicle? The red brake controller wire should only be getting power when you step on the brake pedal. If you are not getting any power on that wire with the brake pedal depressed then you may have it attached to the wrong brake switch wire (if it is hardwired into the vehicle), the red wire is in the wrong location in the plug (if it is a plug in application) or you have a blown stop light or CHMSL fuse. I would need to know the year, make, and...

• What Connections are Needed Under the Hood of a 2000 Chevy Silverado to Power a Brake Controller
  There are a couple of connections that need to be made under the hood of your 2000 Chevy Silverado in order to make the brake controller and 7-Way trailer connector functional. I have included a link to our FAQ article that explains how to make the connections and I will also outline them here. Under the hood, you will need to remove the rearward bracket in the corner closest to the driver. You will then remove the upper and lower covers of the accessory fuse block. Next to the fuse...

The cutout I added is from a link to a help article on installing a brake controller in 1999-2006 Chevy/GMC pickups.

• No Trailer Brakes After Brake Controller Install on a 2000 GMC Sierra
  It sounds like you are trying to install a brake controller on your 2000 GMC Sierra. If that is the case then there is actually a plug in adapter available like the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers part # 3025-P depending on what brake controller you have. If this is what you are using and you have a factory 7-way then the likely cause of your problem is a blown CHMSL fuse.

• No Power on Red Brake Controller Wire when Brake Pedal Pressed on a 2013 Toyota Tundra
  The wiring harness you should be using on your 2013 Toyota Tundra is # 3040-P. While it is unlikely it is wired incorrectly it is possible. You can use your test light to test the connector on the vehicle (where 3040-P plugs into) and see if it has power when you step on the brake pedal. If it does then check to see if the red wire is connected in the corresponding location in the harness. If not you can move it. If there is no power then there is something amiss on the vehicle side...

• Will a Brake Controller Work with a Factory Installed 6-Way Trailer Connector on a Chevy Silverado
  A factory 6-Way is certainly not all that common but it will have a brake output circuit and plugging in a brake controller will work. But there may be some connections that you will need to make under the hood to make everything fully functional. I have included a link to our FAQ article that covers the under hood connections that you will need to perform if they are not completed already. Please note that on a 6-Way trailer connector there are 2 ways that it could be wired. The center...

• Brake Controller Port Location for a 2000 GMC Sierra Pickup
  If your 2000 GMC Sierra is a Classic model, then it will not have a brake controller port. You will need to hardwire in the brake controller and run the wires back to the 7-Way. You would need a part # ETBC7 and some sort of a 4-Way connector. Then you would wire the brake controller to the 7-Way. If your truck is not a Classic model the port should be located underneath a black cover behind and to the left of the brake pedal. I have included a link to a video of a brake controller...

• Recommended Brake Controller and Wiring Adapter for a 2001 Chevy Tahoe
  If the trailer has electric brakes, you will need a brake controller to actuate them. GM didn't start offering a factory brake controller until a few years later. I would recommend the Tekonsha Prodigy P2, part # 90885. The Prodigy P2 is one of our best selling brake controllers, because it is very easy to operate. You will also need the Brake Controller Wiring Adapter, part # 3025-P that would allow the controller to plug into the port located in the junction box under the dash. We...

• Availability of Brake Controller Adapter for 1997 Chevy Silverado
  GM did not start equipping their trucks with the under-dash brake controller connector until the 1999 model year. That being said, you can still wire your pickup for a brake controller. If your pickup has no trailer connector at the rear bumper, you can get a T-one wiring harness, part 118315. That will give you the 4-pole plug. You will also need the ETBC7, which is a kit that gives you 7-pole plug and has wiring which is run to the front of your vehicle for the brake controller. We...

• Tow Package Wiring Connections Under the Hood of a 2001 GMC Sierra with Factory 7-Way
  First, you can see if power is getting back to the 7-Way by having someone sit in the truck and apply the manual override lever on the brake controller. While they are doing that use a circuit tester such as # 40376 or a meter if you have one to test the pin in the 5 o'clock position on the 7-Way. If power is getting to that location when testing then the connection is already made and you won't have to do anything. If the there is no power you can run a wire manually from the blue...

• Trailer Brakes Locking Up on 2002 Silverado with 6-Way Trailer Connector
  I suspect that it is not your brake controller that is causing your problem, especially since this is occurring when the controller is disconnected. There are two accepted methods of wiring a 6-way trailer connector. One method uses the center pin of the connector for the 12-volt accessory circuit, the other uses the center pin for the brake output circuit. If the vehicle is wired using one method, and the trailer is wired the other way, the trailer brakes will immediately receive 12-volts...

• Tekonsha Trailer Brake Wire Harness, # 3025-P, Recommendation for 2000 Chevy Truck
  The difference between the 3025-P and the 3015-P is the pin locations of the wires on the orange connector. The reason for this is because the orange connector on 3025-P is wired to work on most GM vehicles from 1999-2002, such as your 2000 Chevy Pickup. The 3015-P is wired to work on most GM vehicles from 2003-2006. The orange connector on both harnesses are the same, but the pin locations for the different wires are different. It sounds like you have 3015-P and the wires are not making...
