hi guys,
I wouldn't mind betting that there is a diode as well as a resistor in the module. The diode will block the 12v from the brake light circuit feeding back to the DRL / sidelight circuit.
In the video, the module has a Red and a Black wire to ensure that it is the correct way round, not two wires of the same colour which might be the case if it could be wired either way round (i.e. just a resistor)
I Would suggest using a 1N5402 diode which has a 3A rating. You might need to adjust (lower) the ohms value of the resistor slightly, as the diode will contribute to the circuit voltage drop.
The diode and resistor are connected in series. The "line" on the diode (at one end) would connect to the brake circuit (black wire), the other end of the diode connecting to the +12 from the DRL via the resistor (Red wire).
The mod is at your own risk. You will need to check with a multimeter as the above is a logical assumption and no liability accepted.
