Ok im swapping in a obd2 ls, but i will be using obd1 ecu, What is the sensor on top of the intake manifold to the left of the map sensor?

I bileve it is the "Evap Purge valve" If so what do i do with it? cause there is a place for a hose to hook up and a clip.

 

If you have the evap purge on your cars firewall anyway, just remove it from the b18b intake mani.
