This is a common problem that I have seen when using the factory connector on your 2019 Toyota 4Runner. The ground wire for the brake controller is not capable of supporting the negative power from the Redarc Tow-Pro Elite # RED44FR.
Redarc has their Plug-and-Play Wiring Harness # RED49FR that includes an additional ground wire that needs to be connected to a good ground source on your 4Runner. You can try splicing in an additional ground wire on your current universal harness to get... view full answer...
I know you said you checked the fuses, but on your 1999 Ford F-250, the Power Distribution Box and Trailer Tow Relay Blocks are located in the engine compartment near the brake master cylinder, not to be confused with the Fuse Panel located below and to the left of the steering wheel.
There is only one fuse that is tied to your trailer running lights inside the Fuse Panel:
Fuse Location 28 - 10 amp - Brake Shift Interlock, DRL Relay Coil, Speed Control Module, Backup Lamps, Trailer Tow... view full answer...
The easiest way to determine what could be causing the issue with your Redarc Tow-Pro Liberty Brake Controller # RED24FR, installed in your 2022 Toyota 4Runner using the Plug-and-Play Wiring Harness # RED49FR is to check the fault code chart in the installation instructions.
There are a number of different fault codes that indicate the problem and solution. I have included pictures of the fault code chart here for quick reference. If you you need further help with this, please let me know... view full answer...
First thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached.
If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring. That would mean that problem is either due to a ground issue or a short issue.
Make sure that the trailer side connector are clean... view full answer...
Some vehicles will only supply power to certain accessories when the key is on. Others will allow power to them all of the time. For the 7-Way trailer connector, having 12 volt power all of the time is not an issue unless there is something connected to it that is drawing power. Otherwise, think of it as a really long battery terminal.
The brake controller, when powered on but not performing any function, draws very little power. But it should not display anything when there is no trailer... view full answer...
If the braking action on your trailer is a little delayed when using the Tekonsha Prodigy P3 Trailer Brake Controller # 90195 then there are a few things to look at. The first being the power setting for the P3. The power output can be adjusted using the boost on the right or the power level buttons on the left. Please note that this brake controller is proportional so if your tow vehicle isn't moving then it won't send a whole lot of power back to the trailer. You will want to use the... view full answer...
A weight distribution system is not designed to accommodate the space needed for a swivel jack, since typically A-frame jacks are used on A-frame trailers. If the swivel jack and weight distribution system are not working together, you will want to move the swivel jack to provide the necessary room for the weight distribution system.
Another option is to replace the swivel jack with an a-frame trailer jack. We offer several A-frame jacks with wheels already attached and many other a-frame... view full answer...
Since you already tested your vehicle and it sounds like it checks out, the problem must be on the trailer side. I'm not sure where you tested the blue wire on your trailer so we will start there.
Using a circuit tester like the # PTW2993, check the brake output wire right after your 7-way connector. If you have power here then there is likely a short somewhere in the wiring. If you can't find and repair the short you could run new wire using # 10-1-1.
If there is no power immediately... view full answer...
The problem with your running light fuse blowing as soon as you turn on the 4Runner headlights could be caused by any of several problems.
One possibility is that the wiring harness you have on the 4Runner does not have the required current capacity for all of the lights connected to the running light circuit. We offer two 4-pole harnesses for your vehicle; part # 118341 and the higher-current-output Curt harness # C55341. If you recently added extra lights to that circuit, then that could... view full answer...
The problem you describe would usually make me suspect a poor ground connection on the trailer, but it seems you've eliminated that by trying other trailers on the vehicle. Just to be certain, check the spot on the vehicle where your converter grounds to the vehicle frame or chassis. Make sure this grounding point is secure and not corroded. To make absolutely sure, check the grounding points on the trailer as well (where the trailer connector grounds to the trailer tongue

The best I can do is give you general troubleshooting if your lights are not working, but I've never heard of a trailer not being compatible with a vehicle, as that doesn't make a whole lot of sense, though admittedly I could be missing something. That said, for some general troubleshooting, the first thing to do is take a look at your owner's manual to locate any trailer fuses or relays and ensure they are all there and in working order. If they are, in order to determine the specific... view full answer...
That certainly sounds odd. Here is what I would try:
First, unplug the brake controller for 5 minutes and plug it back in. This will perform a hard reset on the controller which is sometimes necessary after a new installation.
If that doesn't work, grab a circuit tester with an incandescent bulb, like part # PTW2993, and test the 5 o'clock pin on the 7-pin trailer connector on your 4Runner. This is the pin for the brake controller. The load from the circuit tester will trick the brake... view full answer...
Are you using the # 3041-P adapter? It's the correct one for your 2018 Toyota 4Runner. Test the connector under the 4Runner's dashboard with a circuit tester, like part #PTW2992, to test for power. If there's no power start by checking the fuses.
If there's power at the plug reconnect the harness to the vehicle and test the pins on the other side of the harness. Check the pins at all the connectors and make sure none are bent. They're fairly thin so they get bent pretty easily. They... view full answer...
Typically there is a white, green, brown, Yellow/Green and brown, and a yellow wire so since you do not have a dedicated yellow wire you will need to test wire functions by using connecting the brown, green, yellow/brown, and green brown one at a time to the positive terminal of a battery while grounding the white wire and seeing which functions come on with each wire. Since the colors on your old connector are not standard you will need to make the connections by function and not the color... view full answer...
The indicator light on the controller should be green when a trailer is connected to the trailer connector at the rear of the vehicle. When the brakes are applied the light should turn red. If the black wire from the POD is not connected to constant 12 Volt power the indicator light will flicker. The Reese Pod brake controller should be connected as follows.
White - Ground
Black - 12 Volt Constant Power
Red - Cold Side of the Brake Pedal Switch
Blue - Trailer Brake feed to Trailer Brakes

I contacted our representative at Redline about the issue you are having with your trailer brakes and your 1996 Toyota 4Runner. He informed me that there should be 12 volts of power at the trailer brakes if the brake controller is putting out 12 volts.
Start with your brake controller. Review the set-up instructions that came with your controller to make sure it adjusted correctly. Then, use a multimeter like part # PT89ZR to check the voltage on the blue output wire of the controller.... view full answer...
The Hopkins Multi-Tow 7-Way Blade and 4-Way Flat Trailer Connector # HM43374 referenced in your question is confirmed to fit your 2004 Toyota 4Runner as long as it is equipped with the factory tow package. Since the trailer lights work fine when connected to your wife's vehicle, the issue certainly seems to be on the vehicle side of your 4Runner.
I recommend testing the wires just behind the connector with a circuit tester like # PTW2993. If you are receiving power at the wires, then... view full answer...
I spoke with my contact at Tekonsha, and the problem is most likely a bad connection from your Tekonsha Prodigy P3 # 90195 to your 2008 Toyota 4Runner.
If you have the Plug-In Wiring Adapter, then you should start by replacing that. It is listed on our site as part # 3040-P.
The other option is if the P3 was hardwired in using a pigtail like part # 20127. If the connector was hardwired in then you will want to replace that instead. You can use Butt Connectors # DW05745-5 to help accomplish... view full answer...
I do not have any specific information about what color wire feeds the running light circuit to your OEM 7-way on your 2005 4Runner. Vehicle manufacturers have been known to vary wire color within the same model year, so wiring by color does not always work.
If you can access the rear of the connector, and find the terminals where the individual wires attach, the wire that feeds the pin in the 1:00 position will be the running light circuit. I have linked you to our Wiring FAQ article... view full answer...
I spoke with my contact at Aries about this and he stated the most likely problem is the support brackets on the top of the guard. It is recommended to check the bolts periodically and make sure they haven't vibrated loose. This is fairly normal and can be helped by using Loctite # LT37643. view full answer...
