General Maintenance & Repairs - Need help with plugs.

Can anyone tell me how may plugs the EGR Valve is supposed to have?I took it off the same time i put my new intake manifold and cam in. i put the motor back together, but i have 3 plugs on the passenger side that I can't remember what they are. i know at least one of them went to the EGR but i cant figure out the other two. Car starts up fine, but now my rpm tach isn't moving. I never messed with the CKP or unplugged it, so i'm not sure why its doing that. All the other gauges work jut fine. If i can find my damn camera plug, i'll post some pics. thanks.

here are the connectors
