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...

run a wire from the OBDIIa A20 to your cluster tacho input
