Expert Answers about Toyota 4Runner


  • Can The 2022 Toyota 4Runner Factory Pigtail Be Used When Installing A Redarc Controller?
  • The only differences between the factory pigtail and the Redarc Pigtail # RED49FR (Redarc part number TPH-021) will indeed be the external ground and a diode pre-installed on the red wire. There were a few issues with brake controller wiring in the past and this was the quick and easy fix for the issue. As there is a diode included in the pigtail, you will need to add one to get the Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR working properly. And just as a side note, I really...

  • Brake Controller Installation on 2012 Toyota 4Runner
  • Installing the Tekonsha P3 # 90195 on your 2012 Toyota 4Runner is indeed a plug and play proposition.

Plug it it, ground the white wire and you're good to go. I've linked you to an installation video on an older model 4Runner, but the installation will be similar on your vehicle. The linked instructions for the...

  • What Is Green Wire for on Factory Brake Controller Harness for 2019 Toyota 4Runner
  • In regards to the green wire on the factory harness, this won't be used. It's for an illumination circuit that is not used on most newer brake controllers. The correct harness you need to install the Redarc Tow-Pro Elite Trailer Brake Controller part # RED44FR on a 2019 Toyota 4Runner is the Plug-and-Play Wiring Harness for Redarc Tow-Pro Classic or Elite Trailer Brake Controllers part # RED49FR . If you want to use the provided factory harness you can instead use the Universal Wiring...

  • Will WeatherTech Cargo Mat WT40486 Need to Be Removed to Use 3rd Row Seats in 2015 Toyota 4Runner
  • The third row of seats on a 2015 Toyota 4Runner (if equipped), is so close to the rear door of the vehicle when it is up that you would have to either roll the mat up so that it could fit behind the rear seats and not obstruct the rear window or totally remove it.

  • Is 2016 Toyota 4Runner Pre Wired for a Brake Controller
  • If it has the factory 7-way trailer connector, your 4Runner will indeed be pre-wired at the factory for a brake controller. The Tekonsha Primus, part # TK90160 you'd looked at is an excellent brake controller that would work very well for you. You'll also need the # 3041-P brake controller wiring adapter, which would plug into the factory connector as shown in the installation video I've linked for you.

  • Installing Brake Controller on 1997 Toyota 4Runner
  • Since you already have a 7-way, you won't need the whole # ETBC7 kit. If your 7-way/4-pole is an adapter like # 37185, simply extend the blue wire from the adapter to the output circuit of the brake controller. You'll need a brake controller like the Curt Triflex # C24VV, the # 5506 install kit and the # C51515 Curt Brake Controller Quick Disconnect harness. If you need the 12-volt accessory power circuit enabled, you'd also need a 40 amp breaker, part # 9510. If you look at the installation...

  • Wiring in a Brake Controller to a 2013 Toyota 4Runner Using Factory Toyota Harness
  • Not a problem. You will need to attach the red brake controller wire to the green/yellow wire (vehicle stop lamp switch). This wire tells the brake controller that you are stepping on the brake pedal. It is a dedicated brake light only signal. The green head lamp switch wire will not be used. It would normally be used for an illumination feature which most brake controllers do not have. Just tape it up and stow it out of the way.

  • Do I Need M12 Bolts to Install Curt Hitch on 1999 Toyota 4Runner Without Tow Hooks
  • Since the Curt Trailer Hitch Receiver # C13087 installation requires removing and reinstalling M12 bolts from the tow hooks on a 4Runner you will need to acquire M12 bolts for the installation on your 1999 Toyota 4Runner otherwise you'll only have half of the necessary hardware installed which can be dangerous. It looks like all of the hitches that fit your 4Runner require these bolt hole locations to be used as well. If you plan on using this hitch for towing I also recommend picking...

  • Does Skid Plate of 2016 Toyota 4Runner Need to Be Removed to Install Westin Sportsman Grille Guard
  • You would not have to remove the skid plate. I checked with Westin and they do not have any notes about removing the skid plate of a 2016 Toyota 4Runner nor is there any mention of it in the install instructions. I attached an install photo from the instructions that shows that the Westin Sportsman Grille Guard # 40-3605 that you referenced actually attaches to the vehicle through the bumper and not from underneath the front end where the skid plate would be. The arrow points to the mounting...

  • How do Tail Lights in Submersible Trailer Tail Light Kit Secure to Trailer
  • The Submersible, Under 80" Trailer Light Kit with 25' Wiring Harness # TL5RK has mounting studs, nuts included, that are 2 inches on center for mounting to a metal mounting bracket. The bracket must be attached securely to the trailer frame because the lights in this kit get their ground connection through the mounting studs. I have included an installation video and a video review of this light kit for you to check out as well.

  • Parts Needed to Install Redarc RED24FR Tow-Pro Liberty Brake Controller on 2021 Toyota 4Runner
  • I'd be happy to help with that. For starters, you'll need the controller itself, part # RED24FR. Where you'll go from there will depend on if the vehicle is equipped with the factory tow package that includes the 7-way trailer connector at the rear bumper. If that's the case, you'll also need the # RED69FR Toyota-specific brake controller wiring harness. To mount the control knob, you could simply drill a hole in an empty switch knockout or a use a # 331-TPSI-002 mounting bezel which would...

  • Wiring to Look for Installing Westin Lighted Running Boards for 2022 Toyota 4Runner
  • Thank you for the purchase of the Westin Molded, Lighted Running Boards w/ Custom Installation Kit # 27-0005-1945 for your 2022 Toyota 4Runner. According to my research the driver's side trigger wire is a dark green and then a purple after the junction connector and then the passenger's side is gray and then light green after the junction connector. You'll need to use a circuit tester to verify these functions prior to making any splices into your wiring. Once you have the correct wires...

  • Where to Run the Ground Wire of a Tekonsha Plug-In Harness # 3040-P on a 2005 Toyota 4Runner
  • When we installed this Tekonsha Harness # 3040-P in a 2004 Toyota 4Runner similar to your 2005 we used a trim panel bolt and it worked fine. If you check out the video I attached you can see exactly what bolt I am referring to. I also attached a pic that I took from the video that shows the bolt and the wire as well. Fast forward to the 1:30 area to see the portion of the video that deals with the ground wire.

  • Brake Controller Installation Port Location on a 2013 Toyota 4Runner
  • The # 3040-P adapter for Tekonsha brake controllers plugs into the 5-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal. See the picture and install video I attached. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how...

  • Why is there a Second Ground Wire in Brake Control Wiring Harness # 3041-P for 2017 Toyota 4Runner
  • The grounds on many Toyota vehicles including your 2017 Toyota 4Runner has proven to be insufficient so an additional ground wire has been added to help. There is likely an existing ground location under the dash you can use or a bare metal surface that would be perfect for a ground. The firewall is one option. Just as long as it isn't a painted or coated surface and just bare metal it will work.

  • What Gear Should 2017 Toyota 4Runner TRD be in When Towing
  • Having your transmission in OD (overdrive) would be fine when towing a trailer with your 2017 Toyota 4Runner TRD. If you were in a super hilly area and you noticed the transmission shifting up and down a lot it would be a smart idea just to leave it in D (drive) so that it wouldn't be shifting as much. Most normal towing situations where you are under the capacity of the vehicle wouldn't require that though. From what I found online though it looks like your vehicle has a 5,000 lb capacity.
