1. Where is the A/C low side port? I have one port on the right side firewall and near the right front headlight?

2. I have three wires inside of the drivers door with plugs. What do they attach too? I'll tell you that my BMW does not have a cold weather package. They don't attach to the power window motor, power mirrors, or power locks. The only button located on the drivers door is for adjusting the mirrors. The wires are in the same wire harness as the power windows and come from under the dash. What are they for?

Is R-12 in it? The plugs are for equipment options not installed on your car.
