As some 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 peoples...

Always use the original engine harness from your car and modify it to fit the engine. After that, if you are using a different ecu, get an ECU Adapter.

 

^^ very true.
