Engine temp correction is the same eg. uses the coolant temp sensor. The fuel temp sensor does bugger all and the fault code can be removed by wiring in a 330K resistor to ground from the ecu pin 36.
Other than that some find that the exhaust temp light comes on when they turn on their aircon, if so cut wire at pin 33.
The z32 only uses one knock sensor if you do not change the wiring at all the front sensor is used, I would use the rear sensor wich means you need to splice wire from pin 24 onto pin 23.
