there are 2 connectors behind the intake manifold on my d15b one is drectly on the runner the second is on a unit with a **** and vaccum line going to it. What are the purpose of these to connectors. Or even better Where do each of the two wires on both connectors go to on the ecu?

 

No body knows what these 2 connectors are??

 

Connector A is the intake air temperature sensor by the sound of it, Connector B is definately the purge solinoid. The wiring should already be in your car for both.

 

my car is a 99 and i swapped a d15b obd1 and those 2 connectors arent tehre but i have the plugs so ill just run the wires direct to the ecu

Ahh, I see, intake air temperature sensor is still on 6th gen civics i believe, but if memory serves me correctly it now goes into the intake tube instead of the manifold. The purge solinoid i can't say i recall seeing on 6th gen though. Here are a couple of links to OBD1 pinouts, hopefully this helps.
