look on the right hand side of the diagram. notice how one says imput and the other says output? that is the kee. signal comes from you MAF into the white wite (imput) then gets edited by the SAFC and goes OUT the yellow wire (output) inot the ECU so the ECU sonly sees the edited signal.
if you can't get that you may want too look into getting someone else to help you out on this one.
and the ground it in the direction AWAY from the ECU and 3+in past the connection of thre brown wire. it's best to use T splices to put this in. (1.99 a box at napa)
