red and black would be the power and the green would prolly go to the O2 sensor wire in the ecu loom

take not of the wires that come through the floor of the cabin just to the left of your knee/feet in a normal driving position ;)

the black and red are for ignition and ground (don't connect direct to battery as the light will be constantly on)
