2002 Chevy running lights.....

I'm not 100% sure what size resistor, but there's a way to find out....unplug the connector to the BCM that houses those 2 wires, make sure that it is bright out, and check the resistance across those 2 wires with an ohm meter. I'm sure that a resistor will be just as good if not better...I just went with an LED since it was a "diode", much like the photodiode that changes resistance with the brightness of light. I just picked an LED that was slightly off. When my lights do accidentally come on by themselves, I can actually reach under the dash and touch the LED for a few seconds and the heat from my hands warms it up enough to turn the lights off lol.
If you do use a diode, it must be wired in correctly, positive to grey, negative to white I believe. If you use a resistor, make sure that it's insulated as it will generate heat...as little as it may be.

With the correct resistor you will not need to reach under there...it just happened to me the other day actually. I plan to eventually check the resistance myself and get the correct resistor or LED, but since the "accidental auto on" only seems to happen a few times a year, it hasn't bothered me that much.
