immobilizer problem
 

hi guys ,
i have a 98 integra type r with no ignition key i bought it from a salvage yard to turn into a race car .i am in the process of trying to start the engine . i have worked out what most of the wires do from the immobilizer to the ecu apart from one which is red from terminal 22 the engine now turns over but does not fire up i need to know what voltage i need to send down this wire if any or is it to be earthed i dont want to fry the ecu by sending to much voltage down it. the no22 terminal is of the ecm 31p connector
