You're close, it's pin 7 and 18 or seven to ground for 3-6 seconds to get all 5 green and anything past that resets your inspection lights that are there too. I do recommend that the cable you use be fused(a fuse between both ends) and have a second hand there. This link (http://www.noren.com/bmw/e30reset.htm
) gives you detailed instructions and has helped me maintain my changes with no problems instead of having to find someone here with the tool to charge me to set the lights again.
