i have a 1991 honda accord lx and i want to install a racing module and i need to splice it to the IAT sensor line.

the IAT is on the intake manifold on the left (driver's) side of te intake plenum. If you stand in front of the car on the driver's side and then look stratight back toward the rear of the engine compartment you'll see the brake master cylinder reservoir. If you move you're eyes in a straight line toward the engine from the master cylinder to the point where you see the cable for the accelerator running parallel to the front bumper you'll be looking in the vicinity of the intake air sensor. The IAT is bolted into the side of the intake plenum roughly behind the throttle body. It should have two cap head screws (one on each side) and an electrical connector snapped onto the sensor. The connector is probably black in color.Hope that helps

It is an IAC sensor, stands for Idle Air Control and it is located by the fuel injection system. its in a hard to reach spot.
