I have a 94 323 with the GTX ecu. I just got a new tb with the 4 wire tps, I plugged it in and used the wires colour to colour the extra wire inline with pin 6. I also moved pin 19 to 7 but its acting very strang if I slowly accel at idle it gets to about 2200 rpm then drops back to 2000 or so but doens't do so if it's d/c.
