Hello, im trying to get my heaxlight doors opening by the switch. They will open & close by the valve on the cannister. Ive researched & they show a 7 pin & a 8 pin headlamp switch for the RS, with & w/o console guages. I believe i need a 8 pin buti do not know why or where any xtra wires run to console?? Any help plz. Thkx.
