I need a p28 ECU pinout badly, I have looked everywhere but all I could find was p30. PLEASE PLEASE if you know where a p28 ecu pinout is please post it.

Thanks
Dan

 

difference between P28 vs p30 is the knock sensor. everything else is the same.

Ok that is just what I needed, but now there is another problem. I bought a obd2-1 harness off ebay and there is already a wire in the a4 slot where, as I understand it, I am supposed to insert the vtec solenoid wire. Should there be 2 wires or is this a f*ct harness? The wire in there right now is yellow with a black stripe.

Thanks

there should only be one wire in there, your v-tec wire, the harnees isn't fucked you just need to remove that pin without damaging it, be careful there a bitch.

 

I can remove the wire but it goes back tot he obd2 side of the harness, should I remove it from there as well? And then just click in the solenoid wire to the obd1 side?

THanks man
Dan
