Im woking on a civic w/ a h22 obd2 that keeps throwing map codes. I know that the evap purge connector and the map connector look very simular. This civic only has one of these connectors, is there anyway to tell them apart (such as voltage with a volt meter?)

If it is the evap purge connector, how would i wire the map sensor directly off of the ecu harness? I know the red and green wire would get connected to D3 on the ecu harness. What would i connect the second wire from the map sensor to?
