Yes they are different i think are you running your std L6 ecu if so think the TPS sensor wires will require swapping (outer wires)

cos when u use a L8 ina 2wd saff you need to chenge um the other way and use a PF09 TPS(4x4 sensor)

also later looms have a knock sensor located LHS lower block on or near to the bung u take out for breather oil return
