Hi All,

I new received a pump from a Disco 2 to replace the broken pump in my Disco 1 with. The old one had a plug with three wires, whereas the newer one uses a plug with 4 wires. Would you guys have any idea which one of the four I can skip? Or am I stuck here? (PS, I do have the newer plug, as the previous owner kindly send it along together with about 12 inches of wiring!

Thanks for any help!
