Pressing brake causing blinker issue

Have a 1999 toyota 4runner and after hooking up a boat trailer, when I press the brakes my blinkers come on solid. If I turn on the blinkers, without pressing the brake they work but the minute I press the brake it either makes the blinker stop blinking or it will continue to blink but the other blinker will come on solid???

    The trailer is no longer hooked up to the truck and it still does it?
    Also when we towed something earlier this year, the tow messed up the gas gauge in the truck, now when the truck is empty it still says it has 1/4 tank left??

    Will that correct the gas gauge too or do we have to do something else to fix that?

The trailer harness that was installed probably has a short inside the box that distributes power to the trailer pig-tail. Remove the trailer harness. You problem will be cured.

    That is possible, if the harness wires are routed over the fuel tank from the factory connector under the LF seat. If the harness you installed is just connected to the taillamps (an aftermarket harness), then, no. I would think that you have a bad fuel sending unit in the tank.

Any trailer lighting harness will have seperate wires for brake and signal circuits. The brake circuit from your 4Runner must be connected to the signal wires of your trailer harness. Check the color codes.

Try unhooking the trailer light harness. Then try brake pedal.

This fault MUST have happened during wiring installation.

1999 4runner light not working on trailer


Check the bulbs in the trailer. If you know someone with a trailer that you could hook up to try that too. A large majority of trailer lighting systems use a simple circuit pattern. Like Christmas lights. . . one goes out they all go out. etc. Some boat trailer lights will burn out if they are hooked up when it's backed into the water. The pain of trailer stuff is figuring out if its really the trailer or not. When the cover is off the lights make sure you take a good look at the guts of the light. The brass pathways will actually arc and melt. Ruining the light. If its not the trailer start checking the vehicle connections. Remember not to overthink things and start with simple stuff first. Oh and recruit a helper to push the brakes and run back and forth it will speed things up greatly.

You likely need diode isolators on the turn signal wiring on the trailer, or on vehicle side connector. Your local auto parts store should have what you need, and show you how to install them.

Tow plug


I take it the blinkers and brake lights work ok when not hooked up to the trailer? If yes, then the wiring to the tow hitch is not hooked up correctly. How many wires to trailer pig tail connection? U can have up to 7 depending on what you tow. Check to make sure these wires are hooked up from the truck to tow plug correctly: 7 wired---
brown-Rt turn and brake light, yellow-backup, white-ground, blue-electric brake, green-tail running lights, black-battery charger, red-left turn signal and brake light. Let me know if u have something other than 7 wire, I'll get the wiring color and source info for u.
