thanks for the print out mate what wire would i have to connect to for the air flow signal?

 

b43 - 6

 

that's for the 4 plug earlier classic, you need B136-5.

 

Primera, one question before you connect your gauge: In post #1 you say that

AFR meters are usually connected to the O2 sensor signal, not the mass airflow input (there is no way for a gauge to work out AFR on the basis of mass airflow sensor voltage alone). Are you sure you're asking about the right wire here?

 

aybe i got it wrong mate the instructions said connect the green wire to the air fuel signal so where would it go lol so its b136-5 for the o2 sensior i need to connect to?

 

Yes, that's the O2 sensor signal wire they're talking about there, not the mass airflow.

You were asking for the mass airflow signal wire earlier, so that's probably what Cokes gave you.

It would help us if we knew whether your car was a 1998 or 1999 model year, as the ECU pinouts are different. Look in your engine bay and tell us either what the Applied Model code is (on the vehicle ID plate, nearside suspension turret) or look at your engine and tell us whether the coilpack (the bit with the spark plug leads coming out) is in the centre of the inlet manifold (i.e. immediately in front of the throttle body) or mounted to one side of it. Then we can help you properly rather than guess a bit.

 

my coil pack is in the centre of the manifold mate and its a 1998 on the log book what version does this make my subaru?

 

looking for ecu c7 pinout ??? anyone have it ?

 

I'm sure it's a b135-5 you have misread the pinout can anyone proof read it to confirm before I hack up my wire harness anymore cheers?
