Another Engine Wiring Question Pics Attached

Found these three wires not plugged in under the hood. 

 

After a  bit or research I found the green/white goes to the auto choke, the red/black goes to the starter and the brow/black goes to the coolant temp sensor.

 

Choke and starter were easy, now where does the brown/black wire go? where is the coolant temp sensor on these cars, I can't seem to find a picture of it online.

 

Also there is a spade on the carburator that does not have a cable, can someone help identify this sensor (third picture below)

 

Thanks in advance

There is the coolant temp sensor! dam I should have gone to bed before I sent this post at 1:47am last night  :mellow:

 

Thanks guys

 

From the wiring diagram:

brown/black = coolant temp sensor

brown/white = temp sensor <-- (I'm assuming this is the intake manifold air temp)

 

Still trying to figure out what this spade connector is though, it's hard to see but it is right in the center of the pic.

Idle cut off solenoid, I'm pretty sure. I remember this from when I pulled my old Solex off! Good riddance with it! You gotta get a Weber on this gal!

 

 

webers have one also, and it is for good reason. It prevents the motor from "dieseling" when you cut the ignition. Otherwise fuel will still flow and if the engine is hot enough it may keep running even without a spark to ignite the mixture.

The 02 doesnt need em. I've done a lot of miles on mine with no cut offs and it diesels about once a summer for one hit, then settles down. Ive parked it after long hot highway drives and heating it up after hill climbs REALLY good (into the red good) and hasn't dieseled. So the Webers are OK without em. Other cars do need them though so your point is valid.
