Video Transcript for Trailer Brake Controller Installation - 2005 GMC Sierra

Today, on a 2005 GMC Sierra, were going to be installing Hopkins Flex-Mount brake control, part number hm47297. In conjunction with Hopkins direct fit brake control adapter which is part number hm47795.To begin our install, were going to mount the Flex-Mount display unit here in the center console. First, well remove the center console trays and route the wire up through the pre-drilled hole in there. Well follow the 12-volt power supply back down through the console. Then, well zip tie the wire to the 12-volt power supply wires to secure it in place, cut off the excess from the zip-tie and re-install the panel.Then, well secure the Flex display in place using double sided tape. Now, to install the Flex control system were going to mount it on the side of the center console, that way its easy to access all of the different controls as well as the manual override.

Before we tape it in place, were going to route the wire back behind the paneling and then to secure the flex control, just use double sided tape which is provided. To mount the smart box, were going to follow the manufactures instructions which say to mount it to the side of the center console and were going to use double stick tape here. Then, were going to connect the flex display and the flex control to the smart box. As you can see the connectors are two different sizes, then just plug them into the back of the smart box.Now, were going to connect the plug-in simple adaptor in the vehicles junction box. The first thing we have to do is remove the plastic nut and then pull the junction box cover off and before we plug the harness in, were going to have to connect the red wire.

On this particular adaptor the red wire does not come connected, its going to depend on your vehicle year as to where it connects.Using a test light, weve already determined that it will be in the top right for our application. Our harness is going to install in the top row, the port that is second from the left. Then, were going to put the cover to the junction box back in place and screw on the plastic nut. Then, you want to zip tie the harness in place here and were just going to follow the manufactures wiring, securing as you go. Tuck in the wires and clip all of the zip ties.

Then, well make the connection with the smart box. That completes installation of our Hopkins Flex-Mount brake control part number hm47297 and the Hopkins plug-in adaptor part number hm47795 on our 2005 GMC Sierra.

Appears to be well made, leads are a good length, and the instructions are clear on where to locate the red wire by year, and the blue fork fits fine. The plug fits the location correctly, but I can't get the snap to engage to ensure it won't back out in the future. 550745

I have not had any issues with the plug backing out after a year.

Great concept, ALMOST made the job a snap. The only problem was that the ground connector in the plug that snapped into the panel in my truck wouldn't make solid contact with the pin in the panel. After an hour of troubleshooting I just took the ground wire out of the connector and gave it a good ground, then it worked flawlessly. 40345

2011 GMC Sierra

I bought the Hopkins Brake controller and haven't had the chance to use it yet but in a few weeks I will have a camper in tow. I bought the wiring adapter for my 2011 GMC Sierra WT w/ tow package but didn't realize until I tried to install it that GMC stopped building an available receptacle under the dash after 2007. I still had to buy pins from Radio Shack in order to make the wiring adapter compatible with my truck but with a little ingenuity I was able to get it all installed. 137691

  • Parts Needed to Install a Brake Controller on a Chevy Colorado
  • A plug-in brake controller wiring harness is not available for the 2005 Chevy Colorado. The vehicle requires a hardwire method to install a brake controller using a 4-Way trailer connector, if needed, # 118301, and a 4 and 7 Way Installation Kit, # ETBC7. If your truck already has a factory installed 7-Way, you will still need to do some hardwiring. You will need brake controller installation kit # 5506. With the included wire, you will connect the white wire in the install kit to the

  • Impulse Trailer Brake Controller Shows Inconsistent Display and Can Not be Set to 30
  • The first thing I recommend is to engage the manual override on full and then let it snap back into place. Do this several times to clean out the contacts inside the controller. Next, make sure that the trailer and vehicle side connectors are clean and free of corrosion. Corrosion can build up in the connectors but also behind them where the wires connect. There could also be a problem with the trailer brake magnets. I have included a link to an FAQ article that covers how to test the

  • Wiring Harness Needed to Install Impulse Trailer Brake Controller in 2005 GMC Sierra 2500HD
  • You will need to get the proper wiring harness to install a brake controller on your 2005 GMC Sierra. Otherwise you would have to do a lot of unnecessary hardwiring that could easily be avoided using the appropriate connector. If you have a Hopkins brake controller use # HM47795. The wire functions on the controller are white for ground (connects to negative battery terminal), black for 12 volt power (connects to positive battery terminal via a 20 or 30 amp circuit breaker), blue

  • Correct Brake Controller Plug-In Harness For 2009 GMC Sierra SLE w/ Factory Tow Package
  • On your 2009 GMC Sierra that is equipped with a tow package, the wiring to install a brake controller is already ran from the factory and a plug-in adapter is not needed. You will find a bundle of wires below the dash to the left of the brake pedal. The wires should be taped up and tucked up and out of the way. There should also be a label on the tape of the functions of each wire.You will want to connect these wires to the wires coming out of the back of the brake controller (see FAQ). On

  • Hopkins Trailer Brake Controller Does Not Work with Brake Pedal on a 2003 Chevy Silverado
  • The wiring harness, # HM47795, for a 2003 Chevy Silverado, comes with a loose red wire that you will need to place in the connector yourself in the correct location. This red wire senses when you are stepping on the brake so the brake controller can send power back to the trailer. The manual override works independently of the brake pedal so that is why it works. It looks like the red wire should be directly to the left of the blue wire (if the blue wire is at the bottom of the connector).

  • No Power to Trailer Brake Controller on a 2004 GMC Sierra 1500 with OEM Tow Package
  • Just to make extra sure, the red wire should be directly next to the blue wire on the harness. The black wire should be above (or below depending on how you are holding the connector) the blue wire. And the white wire should be in the opposite corner from the blue wire like in the picture I have included. When plugged in, the black wire should have 12 volt power. If it does not then you will check the under hood connections and make sure the corresponding fuses are in the right places

  • Installing a Brake Controller on a 2013 Chevrolet Silverado 1500 z71
  • GM stopped using the plug-in style brake controller connectors after 2007 so there will not be a plug-in port for a brake controller adapter on your truck. Instead, there will be 4 or 5 blunt cut wires taped together under the left side of the instrument panel. These wires can sometimes be difficult to locate, but you should be able to find them near the left side of the steering column. You should see a white wire (ground), dark blue wire (brake output), red wire with black stripe

  • Function of Manual Override Switch on Brake Controller
  • The manual override switch is used to operate the trailer brakes independently of the tow vehicle brakes. This feature is primarily used in the initial set-up of the controller, but the manual switch can be used anytime a gentle brake input is needed, such as correcting minor trailer sway, testing the brakes or when hitching a 5th wheel or gooseneck trailer. Operating the manual switch will usually activate the trailer tail lights, but this can vary according to manufacturer. If you

  • How to Wire a CHMSL on a Cap/Camper Shell on a 2010 Chevy Silverado 1500
  • Yes, the orange wire that you found in the bundle of wires near the brake pedal is the correct wire to use as the power wire for the light on your canopy. You are also correct about the white wire being the ground wire. You will also have to connect the two wires under your hood so your tow package will be functional before the center high mount stop light will function on your 2010 Chevy 1500. I attached an FAQ article on how this is done for you to check out.

  • Hopkins Brake Controller Not Receiving Power 2000 Chevy Silverado 1500
  • Its sounds to me like you may have connected the power (red) wire on the Hopkins Plug-in Simple Brake Wiring Adapter part # HM47795 into the wrong circuit. The red wire will need to be installed into the pin that has power when the brake pedal is depressed. There are only three open spaces on the pigtail in which the pin can be connected to so you will only need to test these corresponding location on the the vehicle's control panel box. You can use a circuit tester like part # 40376 to

  • Red Wire Pin Location on Hopkins Brake Controller Harness for Chevy/GMC Trucks
  • The red wire is not supposed to be in the block on the harness when it is packaged. Hopkins leaves this last wire out so that the same part can be used for multiple model years. The end user needs to determine which slot it belongs in before the brake controller is hooked up. The pin location for a 2006 is different than for a 2002. For your 2006 model, the red wire should be in pin location D as shown in Fig. 4 of the directions that were shipped with the harness. Since you had inserted

  • How to Install the Hopkins Impulse Brake Controller on a 2009 Chevrolet Silverado
  • From 2007 to 2013, GM trucks did not use plug-in style brake controller wiring. Instead, they had 4 (sometimes 5) blunt cut wires bundled up under the drivers side dash. The bundle should have a white tag that lists the functions of each wire. I have attached a help article that explains how to install a brake controller on your truck. I have also attached an installation video on a 2009 Chevrolet Silverado for you to check out. The brake controller in the video is different from your Impulse,

Starting with the 2007 model year, GM stopped provided a port. instead they have included the wiring only which is located under the dash. If you look under the steering column to the left, there should be a bundle of wires held together with a white tag. The tag should also list the wiring functions on it. You can verify the functions using a test light, # 3808. Based on the listed functions of the

  • How to Wire in a Brake Controller in a 2004 Chevy Silverado
  • The Hopkins Plug-in Simple Brake Wiring Adapter # HM47795 should have the red wire run to the pin right next to the blue wire closest to the clip side of the connector. See the picture I attached. The blue wire you found under the hood of your truck needs to be run with a length of 10 gauge wire like part # 10-1-1 (sold by the foot) to the rear of your truck to the brake output circuit of your 7-way. You will need to cut the connector off of the end of the blue wire to do this. I

  • Troubleshooting Hopkins Impulse Brake Controller That Causes Brakes to Always Lock
  • There is some troubleshooting you can do but it could also be that the Hopkins Impulse 47235 you have is shot. Test the connection of the red wire (stop light switch) and also take a look at your connectors for corrosion and ensure you have good grounds. If your controller does need to be replaced I strongly recommend going with a proportional controller which will provide you with better braking overall. The best option is the Prodigy P3 # 90195 because of its reliability, effectiveness

  • What Do I Need to Install a Brake Controller on my 1992 Chevy Silverado
  • The 1992 Chevy C/K Series 1500 did not come with a port for a brake controller. Instead, you will need to hard wire the brake controller by first installing a 4-Way, # 118315, and then installing a 7 and 4 Way Installation Kit, # ETBC7. If the Truck already has a 4-Way, then you will not need the 118315. I have included a link to the installation details and a video below showing installation of an ETBC7 kit. If your truck already has a functioning 7-Way, you can use a length of wire

Your truck will require that the red wire be installed in slot A on the connector, which is the correct position for 1999-2002 Chevrolet vehicles.

The wires can be identified by a white label and the color of the wires. The wire colors are (1) Red/Black wire, (1) White wire, (1) Light Blue/White wire and (1) Dark Blue wire and possibly (1) Orange wire. There are two wires
