Help me find my plugs

[EcliptikIlluzio]

I recently rebuilt my engine. It is a 1990. I have most all the plugs from the wire harness plugged into there respectable locations. I have one plug that doesn't seem to go anywhere. It is behind the intake manifold next to the firewall and near the fuel solenoid where you tap the boost gauge into. I have the solenoids, knock sensor, coil, PTM, thingy on AC all plugged in. Stretching the wire it seems to want to reach on the intake manifold somewhere. It is a big 4 prong plug I think or maybe it is the big 2 plug one.

Also there is some type of relay/resistor that is mounted on the back of the big mount that supports the intake manifold. It is a 2 toothed plug with one tooth running horizontally and the other running vertically (like the on on the thermostat housing). Where/What in the world plugs into that?

I hope to find out this stuff by tomorrow so I can finally get the car back on the road. Let me know if you have any ideas where these plugs go?

Thanks.

Hey this me....I'm logged in under my girlfriend and I am too tired and lazy to change the login. Any way I have that link but the plug is further down behind the firewall so you can't see it in the site. Oh well I'll try to read the wiring diagram on the Haynes or look. Any one have any idea what the hell that thingy is on the back of the intake brace? It is like the size of a AAA battery.

Both of these plugs are under the clutch cylinder (one being on the brace as stated before and the other branching off the wire harness that supplies the coil plugs and the like.
