On the rear brake light bulb, the one that you changed to LED, there will be 3 wires, one is a ground wire, the second is a tail light wire and the third is the brake/indicator wire. I don’t know the color of those 3 wires, but you have to connect the supplied resistor between the ground wire and the brake/indicator wire.
in simple terms the normal brake/indicator bulb is a 21 watt bulb, that means it needs 2 amps at 12 volts to light up, your LED light is much more efficient and only needs 1 amp (or less) to fully light up. The cars computer assumes that as the new bulb is only taking 1 amp not 2, the bulb must be failing, so it hyper flashes to let you know a bulb is failing. When you connect the supplied resistor between ground and the wire going to the stop light, it allows the resistor to send 1 amp of current to ground, your LED bulb also consumes 1 amp, so the computer sees a total of 2 amps and thinks everything is good.. the resistor will get quite hot whilst the lights are flashing Or the brakes are on.
i have read that you can disable the hyper flask by programming the the ECU with forescan, and that is the better way to do it, but it is not simple and you have to have a scanner/programmer tool so the resistor is much easier.
hopefully this explains what the resistor is doing and how/why you have to connect it up. Hopefully someone can tell you the appropriate wire colors.
