Load Resistors for 2018 Toyota Tundra and 2010 Airstream with LED Lights to Remove Error

Question

Question:

The Putco load resistors # P230004A-2 put out 6 ohms resistance each and you most definitely can install them yourself. I've attached a photo of the correct installation method to assist. They will get warm to the touch but you can absolutely install them on the inside of your RV where the wires come in from the tow vehicle. I wouldn't put anything right up against the fins as that would further reduce cooling and increase heat, but you won't have any issue in the location stated. The 7-Way to 5-Way/4-Way Trailer Adapter for Vehicles with Lamp-Out Sensors Towing Trailers with LEDs # C35FR or 7-way # 20142 have integrated load resistors and I tested them at 2.1 ohms resistance.

The load resistors # P230004A-2 will get hot and are designed to dissipate some heat with the integrated fins, but it isn't uncommon for them to get too hot to comfortably touch yet they shouldn't burn you. If they were to get that hot, that is another issue to address. I've checked out multiple forums as this is an issue with the new Toyotas that is frustrating many people and most of the time, it comes down to an issue on the trailer even though there isn't an issue using the trailer with other vehicles which is frustrating because it is very difficult to isolate the issue. You can try to isolate the issue on the trailer checking all the ground connections for bare metal contact, testing your brake magnets, and testing each wire with a multimeter like # BTMT15. Most people find the trailer is fine and the truck is fine and end up with an aftermarket brake controller to solve the error issue which seems to work every time yet is another expense. Many people have used the Tekonsha Custom Wiring Adapter for Trailer Brake Controllers - Pigtail - Toyota # 3031-S along with an aftermarket brake controller like the Redarc Tow-Pro Elite # 331-EBRH-ACCV2 to give a clean look and yet help that error to go away. This is the best solution in my opinion if you can't isolate a trailer wiring issue since the load resistors didn't solve the problem.

Answer 1

It sounds like you have a 7-Way and are using a 7 to 4-Way adapter because the trailer has a 4-Way flat. If the running lights are not working with this set up, the first thing you will want to do is use a circuit tester, like #PTW2993 if needed, and…

Answer 3

If you used the Curt 7-Way to 5 or 4-way #C35FR that you referenced with a trailer that has a 5-way then yes, the reverse light circuit will be active. If you used it with a 4-way then no it would not. That fifth circuit is for reverse lights. There…

Answer 7

Yes, the Furrion Chill RV AC Unit part #FR25PR that you referenced does have a start capacitor built into it which is basically a soft start so that it doesn't draw as much amperage upon start up.

Answer 9

The issue as I am sure you are aware of is that the trailer lighting circuits on a 2019 Chevrolet Silverado 1500 do not send enough voltage to the running light circuit to power the observation system camera. As of September 2019, neither Furrion or…

Answer 11

You will wire a load resistor into the wiring of each light socket that has an LED bulb and flashes. So basically you will need to wire a load resistor into any bulb that blinks or has a dual intensity feature that lights up when the brakes,…
