The error codes you are getting with your Prodigy P2 Brake Controller # 90885 help explain why you are getting intermittent braking. The "S.H" means you have a short in the brake wire during an idle connection and the "P.L." is a power interruption when you hit the brake pedal. This makes sense in the way you described it as I imagine the S.H. is happening before you move the car and the P.L. is happening when you brake.
I imagine there is a short on the blue brake wire somewhere along... view full answer...
There are issues with the ground wire on your 2004 Toyota 4Runner when installing a brake controller like the Redarc Tow-Pro Elite # RED44FR. I know you mentioned cutting off the Tekonsha side of the Adapter # 3040-P which has an additional ground connection tied into the connector. You will need to ensure that this is used since you do not have the Redarc Tow-Pro Wiring Adapter for Tekonsha Brake Controller Harness # 331-TPH-017.
If you used the additional ground wire and it is still... view full answer...
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...
The best way to ensure adequate power for your towing rig is to fully charge both the vehicle and trailer batteries before heading out. A simple tool like the CTEK MULTI universal charger # CTEK56353 will work on both your vehicle and trailer batteries to "top them off" before you head out. This charger has specific modes for both smaller batteries and for car batteries.
If you want to have a fool-proof way to avoid the trailer battery from draining the vehicle battery, you can install... 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...
This sounds like a ground issue. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces.
The light grounds should also be attached to clean and corrosion free bare... 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...
This is a common issue I've seen in many different Toyota 4Runners as they seem to be more sensitive to backfeeding from the red wire of the brake controller to the stop light switch. This causes the issue you're seeing, triggering the ABS error message.
You are correct when thinking that a diode will prevent this from happening but the Tekonsha 3041-P harness does not feature a diode in the red wire; the harness you need is the # 7865. view full answer...
Since you've had the brake controller, brake magnets and wiring adapter pigtail replaced, I think it's safe to rule out each of those components.
You've had somebody tow the trailer around with a different truck without the problem being recreated. Is it possible for you to tow a different trailer that's equipped with electric trailer brakes using your truck? This would effectively rule out your truck as being the problem.
The fact that the problem you're experiencing is intermittent... view full answer...
Since this is the first time you have used the connector on your 4Runner, if it has been awhile since it was installed or if it is factory then there can be some corrosion build up inside the connector preventing it from working. This happened to a friend of mine recently. Scraping out the corrosion will help. Also make sure the main ground is connected to a clean and corrosion free bare metal surface.
If that does not help then use a circuit tester such as # PTW2991 to test the vehicle... view full answer...
Since the trailer functions correctly on your Nissan truck but then blows a fuse once connected to your 1998 Toyota 4Runner, it sounds like there is a short circuit somewhere on your 4Runner.
When troubleshooting, I always recommend starting off by checking the 4-way connector. Make sure that it is free of dirt and corrosion.
Next, make sure that the ground wire on the 4Runner is securely grounded to a clean metal surface and that all of the wiring for the connector is in good condition.... view full answer...
Thank you for your recent purchase of a Curt wiring harness # C55341 from etrailer.
The ground wire connection, which you note you have already re-checked, would indeed be my first suspicion based on the harness' behavior you describe. It can often happen that a weak ground will let just enough current to pass to allow some lights to work but not others. Turn signals, since they do not remain on at all times, draw less current and may often be the function that works while a function like... view full answer...
It sounds like the wiring on your 2000 4Runner needs to be corrected so that the turn signal lights activate correctly and are consistent with the wiring on your other vehicles.
First make sure the tail light connectors are installed on the correct side of the 4Runner. The plug with the yellow wire should be connected at the left/driver side tail light and the plug with the green wire should be connected to the right/passenger side tail light. If this is how it is installed and the signal... view full answer...
The lights in the adapter will tell you that the vehicle itself is sending the proper signals for the directionals, running lights and brake lights. These lights are useful to eliminate the vehicle as being the cause of any wiring problems. It will not tell you of any trailer wiring issues.
If the lights in the adapter indicate that the signals coming out of the vehicle are all operating correctly, but the trailer lights are not working you will have to troubleshoot the trailer. To do... view full answer...
The first thing I would check is the ground wires. You have probably done this, but I would make sure your ground is securely attached to clean area. After that, make sure the power is firmly connected and working in both vehicles using a circuit tester like Item # PTW2993. Next, I would check for loose or pinched wires.
Next, I would make sure your Voyager Brake Controller, Item # 39510, is mounted in your cab at a vertical angle that is between -20 degrees and +70 degrees. Proper... 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 looked up your owners manual for your 2008 Toyota 4Runner and you will want to check fuse location 51 for the 12V function, location 52 for the trailer tail lights, and location number 49 for brake controller. You will also want to check fuse location 57 and fuse 27. There is a towing converter module that is on fuse 27.
You will want to check your paper manual to make sure it lines up with the suggestions above from the online manual for your vehicle.
If all of the fuses are good... view full answer...
For simplicity sake you would be better off using a T-union so that you only have to inflate one thing and wouldn't have to worry about equalizing the pressure. For a union all you need is the part # AL21838. view full answer...
Regarding the ground, if the fire wall is painted, that could be causing a bad ground issue. Just make sure it is on a bare metal surface. You can also check to make sure both the vehicle side and trailer side connectors are clean and free of corrosion and that the connectors are properly grounded.
Next, I would unplug the brake controller and test the vehicle wiring using a circuit tester like # PTW2993 or a multimeter like # PT89ZR. Test the wiring for voltage when you step on the brake... view full answer...
The trailer running lights use a single dedicated circuit from the connector on your 4Runner so if just the right side running lights aren't working then we know the problem is somewhere on the trailer, and not the tow vehicle.
The fact that only the right side on the trailer isn't working actually helps to narrow down the potential cause quite a bit, as the fault could really only be with the tail light itself (which works fine for the brake/turn so we can rule that out) or with the... view full answer...
