    Re: Flasher

    Flashers depend on bulb electrical resistance to "time" the flashes. You need to calculate the proper dropping resistors to insert in each LED circuit.

    IF the flasher system is anything like the earlier 2002's, the flasher is part of the emergency warning flasher switch.

    If only it was as simple as "cutting".

    You are now faced with placing a resistance value of approximately 5 Ohms at 20 Watts in parallel with the BLU/WHITE tracer wire at each front lamp wire harness. The resistance is placed in parallel between the wire and a good clean chassis ground.

    And resistors of that wattage rating must be firmly attached to chassis metal to dissipate the heat produced.

    If Photobucket cooperates, the picture below will illustrate the meat of my description; this is a different year and a different location but the fix for hyperflash is the same. I used Radio Shack consumer resistors and had to fabricate a 5 Ohm resistor using two 10 Ohm resistors in parallel.

    That did not work and I'm unable to load the picture directly to this thread. Send me a private message including your email address and I will respond to you with the picture attached.

    I heard u can cut the trace on the flasher relay board it slows down the flash instead of using resistors
