how do i pull codes? i know, plugnit in blah blah... sorry new to SR swaps but it doesn't seem like there's a port in my car, unless it's the one in the fuse box in the kick panel.....

i checked all today again, TPS, Ignitor, coil pack signals MAF stc... all read out to about 11.8V....

could i test the knock sensor in the same way? if so, what should the voltage readouts of the signal be? or will that even work?
