    ECU/Wiring ... all my issues ;)

    Thanks you everyone for your continuous effort........

    As many of you may know I have had various ecu issues..

    Original Vehicle (OBD2B EM1)
    Below LEFT….


    After engine bay harness Conversion ( OBD2A EK4)
    Below RIGHT ;



    NB. There are 3 plugs on the obd2a engine harness and now im stuck with 2 "A" connectors



    To get the car idling I had to tap the new Fuel pump relay from the obd2a plug to the oly obd2b plug...

    I still have no tacho and am afraid to idle it for long as i am not sure if temp is working either...

    How can i get the tacho to work first?
    how does the cirucit work....
    ECU>ICM>Cluster? or ECU > Cluter & ECU>ICM ?

    I need to know how my cluster is getting fed and from which side of the firwall....



    thanks peolpe...
