What engine/intake setup do you have? Do you have a swap? What trim model civic? If you did swap, what engine was in the car before?Well it has one on manifold, it’s the one that actually goes into the intake pipe itself
Also can’t seem to find the plug that hooks to the one on the manifold though too
When swapping the connectors to do so, I will need to figure out which wires attach to each other. Or will colors of wiring be same on both plugs?The reason I asked about the engine swap details, is because if you have an engine harness that only has the IAT connector protruding from the harness near the intake tubing, then you will not have another random IAT connector just hanging around the intake area. You will only have the one.
If you want to use the IAT at the manifold, the best solution will be to extend the IAT wires over to the sensor in the intake manifold. Once there, you will need to change the IAT sensor connector, as the intake mounted sensor is a different shape than the piping mounted sensor. Source the appropriate connector for the sensor type that is in the manifold and plug it in.
The internals of both sensor designs are the same within the model year realm of all the potential engine/chassis components you've listed, so it should be a plug and play scenario once you get the correct connector.
