I have installed LED Lights in the Back of the truck and Im getting hyper flash issue, I bought resistors to add load on the system for both left and right sides, I tried to install them in the back of the truck ground wire Black to ground and Red to signal light but IT Didnt Help, still get Hyper-Flash. Am I suppose to Install it under the hood some where? if so, Where?? P.S. this truck was turned into a tow truck and the pick-up Box was replaced with a wrecker with sealed LED Lighting for brakes and Signals work on the same lights if this makes a Difference??? Thanks

As you probably know, adding LED lights can cause a hyperflash problem with turn signals. You would need to add a load resistor like # P230004A to every light that was changed to LED. You have to make sure that the load resistors are installed correctly. One wire will connect to the power wire going to the bulb. The other wire you will ground to the truck frame or grounding point. I have included a picture that shows how it should install.
If you are still having hyperflash problems you can install a heavy duty flasher, # 39552.
