Sorry to ask again. Can't find where I ask about it before. Still have hard time trying to find out the dome supervision wire. Some instruction says white 4-pin plug with pink wire. I took out the front map lights and found a pink wire with 2 silver marks. I then find one behind driver's kick panel, where there are 4 wires+1 fog light wire. I tapped into it and it always shows 12V as soon as the car is ON. I remove the plug (the one that stacks with another one, as seem in fog light installation instruction) and iMID says "Check braking system" and "Check ABS system". I immediately turn off the car and plug it back in. (Hope that it won't affect safety.) Another pink wire(s) is found with many wires in double row. I remove the plug and all lights go out. But I tap into the pink wire it shows constant 3.x volt (it actually has about 3 pink wire, each with 2 silver marks). Anyway, where can I easily find and tap into the dome light supervision wire?
