Ok, quick question. I wrapped up my install on my 06 WRX this weekend, but Ive got one lagging problem. The integrated module apparently doesnt control the domelight supervision as I had originally thought (via lock and unlock wires). Ive located the domelight wire. It shows 12v when the door is closed and the light is off, and ground when the door is open and the light is on. This tells me its a negative trigger. Since the supervision output from the brain is also a negative trigger, do I still need to wire a relay? More directly, can I just connect the output (200mA -) directly to the dome wire in the car?

You will need to use a relay if you are supplying the bulb itself, the 200mA output is not strong enough supply the light bulb.
