I have a apexi turbo timer and i want it to read my A/F it tell me i need to ground it to the Ecu Ground to correctly read it. But i have no idea where the ecu ground is. Where is the ECU Ground for a p72??
 
the grounds for the ECU, Main Relay and the distributor wiring shields are all connected together at the ground wire from the engine harness that bolts to the thermostat housing - the actual ground locations at the ECU are at pins A23 and A24
