On my Mk4 with 1996 4.6 DOHC I am getting a P0412 error because the Secondary Air system has been removed. I have searched several forums for a solution and found that I can place a resistor into the circuit to fool the PCM into thinking the AIR system is still there.

My problem is that I do not know what size resistor/s/ and where to place them.

I know the AIR uses pin 5 and pin 70 on the PCM. So I am guessing two resistors connected to these two pins and guessing that one end of each resistor is connected to one of these pins and the other end to ground. But I am only guessing.

Can anyone help me?
