Ok so pin42 is 12v I can send that to the vag coil with a resistor for power as I read above I am just curious as to what I do with the oem harness ground and signal wire since the green one is power I’ll leave that one excluded on the vag coils do I connect pin 3 to the oe wire as a signal and then ground it using pin 4 to the brown oe wires or to cylinder head/valve cover (currently I have pin 1 connected to the junction box in the bay for 12v like the n54 guys do with the diy they do) can you help me I’ve gone too far already with this my Instagram is @e36_sonsa

Ok it seems that we got this to work I’m trying to recreate this exact same set up can either you or the other person in this please help me or just simplify what wires go where I really need some help now I’ve got the resistors and the coils and everything I’m just not having success I just need to see or read exactly what wires go where
