Name these plugs

Trying to figure out if any of these need to be plugged in, been about a year since I have messed with a 1G and I have nothing to reference off.

This is the main one. It comes from the harness that has the coolant sensors, this plug has a blue wire coming out of it.

The 2 firewall plugs I believe are emissions related.

First one looks like the one for the sensor closest to the head on the back of the thermostat housing.

The second one is cruise control for the big one and fuel pressure solenoid for the small one.

The second pair the large oval plug is the one you jumper to ground to set timing, Not sure of the other but it does not hook to anything

 

Thanks.

Off that one loom is 2 1 wire plugs like that, the other fits better onto the sensor on the tstat housing as this one does not appear as long, so I was thinking it was to something else, unless I am missing a sensor on my t stat housing. Does that make sense?

I thought all the other ones did not matter, sounds like I was right on them.

The blue one goes in back. I think the front single wire is green or something.

The other is the fuel pump test connector. Should have 12v with the pump running.

Back of the Tstat housing?

Yes, back of the t-stat housing.

 

[GVR4_1057]

Yes, Back toward the bottom next to the head.

 

Found it, thanks guys.

That stupid plug was hiding good. Now to figure out this damn CEL light and I will be driving the damn thing finally.
