I am currently in the process of finishing the de-smogging of my truck. When I got the truck everything was hanging or ripped out. I am trying to figure out what plugs and wires need to stay. I have read through KawaZX636's threads multiple times trying to figure out what I need to keep. On the intake side of the engine how many sensors should be left after removing the emissions? I pulled this picture from KawaZX636's thread but i'm not sure what the connections go to, considering one is labeled with a question mark and battery.

 

Not that it is a lot of help but when I desmogged my 85 I had two sensor wires left over. I think one was a water sensor and cant remember the other one.

 

The "?" label went to a ground noise reducer. You'll want to keep that

 

Hope this helps:


there are 2 for oil,one for water. there is a dummy light in cluster for oil, and if you have center pod, there is another oil wire for actual oil pressure gauge. one is not omitted if center cluster is there, you just have 2 oil system checks.


There should also be a horn wire there(it maybe in headlight loom), and the wire that runs to starter solenoid from ignition switch(larger gauge wire)


If you have voltmeter there will be a 12v switched lead, and electric choke needs the same if you are going those routes. I found some switched 12volt leads there on fender well. regardless you can add these.


I have schematics with wire colors for 1980, 1985, and 1987. I also have an 84 sitting in the yard I could look at to try to give you an idea on what colors and such to look for.

 

the oil pressure gauge wire has a plug that looks like a typical female blade(maybe a little narrower then the others), there is slot down side that slides onto oil pressure sending unit top connector.

 

Thanks for the help guys. Got it all now.
