    I am trying to salvage a melted DRL housing and keep going by replacing it with LED.
    I am at crossroads with how to add the resistor to eliminate hyperflash.

    The socket only has two wires going into them. One of them white with a balck line, other is grey.

    Do I just splice them both and connect the resistor? Does not that mean the resistor will be hot all the time when DRL is on?

    Or do I splice one wire and the other end of the resistor to the trucks metal body?

    Thanks in advance

    Got it working.
    Splied one of the two wires and grounded to bolts that hold the radiator. Works well.
    I had expected to resistor loading only when the turn signal is used, but it seems to loaded all the time, it gets pretty hot even not using the turn lights.
    I dont understand the wiring to fully explain this behavior. Someone out there might know, please help.

    Hey man, I'm doing this mod in the next few days and wanted to confirm that you spliced into the yellow wire on the driver side. And green wire on the passenger. Then grounded the opposite resistor wire to a radiator bolt. No need to touch the white wires (grounds) then correct?

    I will take a look at it tomorrow and let you know. Dont have access right now.

    I was thinking that i could splice in the opposite wire on the resistor that you grounded to the radiator bolt, to the actual ground wire itself thats going into the socket. But if your method is proven to work, I'm running with it lmao. Much appreciated with the fast reply. Get back to me whenever you get around to taking a look

    The LED bulb has hi resistance, so it doesn't draw enough current to trigger the flasher. When you add a 6 ohm resistor it lowers the resistance , the bulb and resistor draw approx 2 amps. In a parallel circuit the total resistance is less than the resistance of the smallest resistor. In this case less than 6 ohms
    so it will draw approx 2 amps...........when the blinker is off there should be no current flowing to the resistor so it should not be hot unless the signal is on.

    Hey..I spliced the non-white on both sides. I say non-white because the second wire on one side is yellow and the other is gray. So spliced yellow and gray. The trick to me was finding the ground. It was different on both sides, so I tried to ground various spots to find one that corrected the hyper blink.

    Having said that, I would not do it again. It looks kludgy. I would get a professional kit and be done with it.

    I ended up splicing into both wires. The colored wire and white(ground) wire. I didn't need to find a location to ground. Was almost too simple being that there was only two wires coming from the socket of the drl lol. Mine ended up fairly clean and tucked but for the money spent and time researching about how to install, wiring, etc. I would much rather have just went with an LED flasher and avoided the need for a resistor. Thanks for the response man
