Hopkins Plug-In Simple Brake-Control Wiring Adapter - Ford
part number: HM47845

Designed for your vehicle with a factory tow package, this wiring harness plugs into the quick-connect harness located under your dashboard and into your Hopkins Agility, Impulse, Reliance or BrakeForce brake controller for easy installation.


  • Connects your Hopkins brake controller to your vehicle's factory tow package
    • 1 Plug is inserted into the back of your electric brake control
    • 1 Plug is inserted into the factory-installed port under your dashboard
  • Requires no cutting or splicing wires for installation - just plug and play
  • Works with Hopkins Plug-In Simple brake controllers (Agility, Impulse, Reliance and BrakeForce)
  • 90-Day limited warranty

Tech Tip: The OEM plug in your vehicle is located under the dashboard to the right of the steering column, behind the black pocket in the dash.

This brake-control wiring adapter will simplify the installation of your Hopkins electric brake controller. Once the brake controller is installed, the harness then plugs into a port under the dash. Because your vehicle has a factory tow package, all the wires for the brake controller have already been run from the 7-way trailer connector at the back of the truck to the plug under the dash. If your vehicle does not have a factory 7-way, additional wiring will be necessary to complete installation.

Video Transcript for Hopkins Brake Controller HM47845 Review

Today, we're going to be taking a look at part number HM47845. This is the Hopkins Plug-In Simple brake control wiring adapter. This is going to fit many Ford applications, so to see if this is going to be a fit for your particular vehicle, you can use the vehicle fit guide located on our website. This brake control wiring adapter is going to simplify the installation of your Hopkins electric brake controller. This simply connects your Hopkins brake controller to your vehicle's factory tow package. This flat plug right here is going to be the plug that gets inserted into the back of your electric brake controller, and then this plug is a custom fit plug that's designed to fit into the factory installed port under your dashboard.

One of the great advantages of a system like this is it doesn't require any cutting or splicing of wires for installation. All you have to do is plug them in until you hear them snap into place, so it's a plug and play system. This is designed to work with the Hopkins Plug-In Simple brake controllers like the Agility, the Impulse, the Reliance, and the Brake-Force. A little tech tip is that the OEM plug in your vehicle is going to be located under the dashboard, to the right of the steering column, right behind the black pocket in the dash. When it comes to the total length of the wire, you're going to have about thirty-six inches to work with, that's just the amount of wiring in between the plugs, and then they do have a couple different spots along the wiring where they're taped together. That's just going to keep the wires bunched up or together.

That way they don't dangle by the pedals on your vehicle or behind the dashboard. I do have a brake controller here today from Hopkins. This is the Agility. I'm just want to show you real quick how this would plug into the port here. Really simple operation, all you have to do is line up the two pieces, push them in until you get it to snap together. It's just as easy as one little snap and push.

To disconnect, all you have to do is lift up on that tab, simply wiggle it loose until it becomes disconnected. That's another great feature of an adapter like this, is you can connect and disconnect from your vehicle or brake controller quickly and easily. That's going to do it for our review of part number HM47845. This is the Hopkins Plug-In Simple brake control wiring adapter. .

Easy install, watched etrailer video to find best way to get to factory plug. Made a custom bracket and mounted slide and led where factory controller is supposed to go. Don't use just db tape to mount the main unit use screws. Last thing you want is it flopping in your feet while on the road. 693791

The item i clicked on was correct and the picture was accurate but i received this part for a newer truck which i can get in any store. I'm not paying one dime for return shipping. I found etrailer and thought it would be a good deal because i install hitches brake controllers and build trailers. But never again. No way in hell would i select the wrong part. Something happened on etrailers end not mine. 14bucks for return shipping in insane. When it's only a few bucks. But still etrail er should take care of it. I can order it on ebay cheaper with free shipping cheaper than the return price to etrailer. Be careful 508728

  • Hopkins Brake Controller Wiring Harness for a 2018 Ford F-150
  • Hopkins does indeed list brake controller wiring harness # HM47845 as a fit for the 2018 Ford F-150. There is a little cubby hole on the center console to the right of the steering wheel on the truck. Behind this cubby hole is the connector you need to plug in the brake controller. I included a drawing of the location.

  • Hopkins Reliance Brake Controller Installation in 1999 Ford F-250 Super Duty
  • You can install your Hopkins Reliance hardwire-type trailer brake controller in your 1999 Ford F-250 by using harness part # HM47715. Just cut off the flat connector, splice the wires to your Reliance color for color using butt connectors like # DW05745-5 and plug it in to the under-dash port as shown in the linked video.

  • Which Brake Controller Should I use on a 2005 Chevrolet Tahoe with Factory Trailer Connector
  • The part you were looking at includes the harness for Ford vehicles. If you want to use the Hopkins Agility, the part number you would need is # HM47294 and # 47795. It has the plug-in harness for your 2005 Tahoe brake controller port. That port will only be active if your Tahoe came with a 7-Way trailer connector from the factory. I would strongly encourage you to get the Tekonsha Prodigy, part # 90885 and adapter part # 3015-P. It is our best selling brake controller and is one of

  • Installing Brake Controller And Wiring Harness On 2015 Ford Flex Without Factory Tow Package
  • I have attached a drawing that shows how the wires are run for the # ETBC7 and brake controller wiring. There is no plug-in adapter available for a brake controller for your Flex with no factory towing package so it will be a hardwire installation. I called my contact at Tekonsha and they said the plug you sent the photo of is not the connector used for a brake controller. You will need to use the circuit tester that came with the # ETBC7 to test the wires on your Flex. The red wire

  • Fuse Location for Brake Controller on a 2005 Chevy Tahoe
  • On your 2005 Chevy Tahoe, if using a Hopkins brake controller you would need connector # HM47795. If it is a Draw-Tite, Reese, or Tekonsha harness you would use # 3015-P. For a Curt controller you would use # C51352. For a Hayes controller you would need # HA81780-HBC. None of these harnesses come with a fuse. It is possible that you are referring to the factory brake controller wiring harness that is included with some vehicles. If that is the case then the fuse for the brake controller

  • Troubleshooting Brake Controller On 2003 Chevrolet Silverado When Trailer Brakes Dont Work
  • There are a couple of items that are causing your brake controller problem. The problem can be caused by either the stoplight wire incorrectly installed, or the adapter you are using is not designed for the brake controller you have. The plug-in adapter from Hopkins we show that is designed to fit a 2003 Chevrolet Silverado is part # HM47795. It is designed to fit certain models of Hopkins brake controllers like Hopkins Agility Trailer Brake Controller (HM47294), and Hopkins Reliance,

  • 2008 Ford F-250 Will Not Start or Crank After Installing Hopkins Brake Controller
  • First let's make sure you are using the proper brake controller wiring harness for your 2008 Ford F-250. For a Hopkins brake controller you should be using # HM47855. It would not hurt to make sure that it is also plugged into the correct plug on your truck. I am fairly certain there is only one though but it never hurts to make sure. If your truck came with a brake controller pigtail from Ford and you hardwired the controller to it then the wire colors would not match up between the

  • Brake Controller Wiring Harness for a Hopkins Brake Controller and 2012 Ford F-150 XLT
  • Brake controller wiring harness # HM47845 is the correct harness for a 2012 Ford F-150 XLT and a Hopkins Reliance brake controller. I have linked a video showing installation of a different controller and harness on a 2012 F-150 but it will be the same with the Hopkins parts on your truck.

  • Recommended Brake Controller for 2013 Ford F-150
  • There are no aftermarket brake controllers designed to mount in the OEM slot. However, I recommend going with the Hopkins InSIGHT Flex-Mount Trailer Brake Controller. It can be mounted anywhere on the lower part of your dash, so while it won't fit into the OEM location, it can be positioned near it or over it. This particular controller uses two small components that are especially unobtrusive. I also recommend using the Hopkins Plug-In Simple Brake-Control Wiring Adapter for Ford vehicles,

  • Recommended Plug-In Adapter For Hopkins Brake Controller On 2013 Ford F-150
  • When installing the Hopkins InSIGHT Flex-Mount Trailer Brake Controller HM47297 on your 2013 F-150, you only need the additional plug-in adapter, part # HM47845 to complete the installation. You plug one end of the adapter into the back of the brake controller and the other end into the brake controller port located under the dash just to the right of the steering column.
