Help me identify my plugs

[Jinaman]

I just finished a headgasket job. I have the car basically assembled and startable. But there are two plugs on a pigtail left over i cant find a home for.
The car is an 84 eta and the larger plug is unique in shape too all the other plugs. They are come off the motor harness kind of underneath the intake mani but looks like they could go alot of places. I lost alot of my markers when working on the car but these are the only two that have me stumped.
This is the first on and it is unique in that it has the extra bit of plastic holding the clip. In the lower left hand side you can see it sticks off the back a little.

This on is located on the same branch and i also cant find a home for it.

I know all the plugs look similar so this sounds like a stupid question but does anybody by chance have an idea.

it would be funny if they clipped together.

it would be funny if they clipped together.

Sorry, but I just literally lol'd.

I'd look for plugs of the same/similar color. Usually the colors will match. Otherwise, I donno what to tell you. There is the online electrical trouble shooting manual.

My bad. Looks like they come off a sensor on a thinner coolant line on coming out of the thermo housing

Each plug has a solid white and solid brown wire coming out of them, but by the time they get to the sensor there is only two brown wires, on the right in the second pic you can see a "Y" in the harness that's were the white wires end. Is this a temp sensor or pressure sensor. I seriously cant figure out were these go.
I noticed a screw on the thermostat housing that threads into a little hole but there isnt anything attacked to it.

does your thermostat housing have all the conectors hooked up to it? there is like 4 all together. i think the smaller 2 prong clip is the coolent temp sensor that feeds to the ecu but not absolutly certain. this diagram is from real oem for my 86e. it shows 4 plugs to the thermo housing.
