Below these instructions are for hooking up an the wire harness on the edge controler to the ICP sensor. Hope this can help you locate the sensor. I personally have not worked on this engine.
Connect the supplied ICP sensor wiring harness to the supplied main wiring harness in the engine compartment. Disconnect the stock wiring harness at the sensor located above the valve cover on the driver’s side towards the front of the engine. Plug the supplied ICP sensor connector into the stock ICP sensor on the engine and the stock engine wiring harness connector into the supplied ICP sensor connector.
NOTE: The ICP connector is on the drivers side of the engine located close to the engine removal ring under the boost hose – Notice the BLUE gasket. The ICP connector is NOT located at the front of the engine, as that is a coolant sensor!
