What is the sensor/plug in the first picture?

What do I need to do with the firewall mounted plugs? second picture.

Third picture. Does it matter which wire goes on what pin for the sensor on the thermostat housing?

TIA!

 

Sorry about the really big pictures. And I also hate how they go sideways instead of down now?

 

pic number 1. Purge solenoid correct? I can just take this off along with the charcoal canister.

pic 2. The firewall mounted thing. One of those are a purge solenoid too. which one? And what should I do with the other plug?

pic 3. Still wondering if it matters which wire goes on which pin in the plug. Going to solder it onto a female plug that fits it.

 

Yellow green and black for thermal fan switch makes no difference. As for the purge solenoid you can use your factory one or if you want to use the obd1 sensor your car should only have 1 (the one with 2 vacuum lines). The other sensor will be your map sensor. I say keep it easy and use the factory ones from the car.

 

Thanks for the reply. I can just delete the purge solenoid correct, along with the charcoal canister, anything else to delete with this? And couldnt I use the map sensor on top of the throttle body? And then just delete the whole firewall sensor thing. ?

 

Yes you can use the throttle body mounted map sensor

 

Thank your si-r
