Black EH6

I recently got my hands on a used cobalt autometer tach. Now I was trying to wire everything up last night and I cant seem to figure out where the 4 wires for the tach are supposed to go. I know the black is ground and the red is power. There are 3 plugs (i believe) on the back of the gauge cluster (which is from an eg si btw.) I need to know which one to tap into. There is one on the left, one in the middle and one on the right. Help appreciated. Thanks

I believe the is a wire for power, ground, tach signal, and light.

Should be green= signal, red=power, black=ground, other (white??)=parking lights (should be an extra slot on your fuse box you can wire to that supplies power with the lights on). Your signal you can hook up to the tacho output on the back of your cluster, all civics have the wire there (it is blue/white I belive).
