240Z & powerfc

[retrotec]

Slowly building up a 25/30 that will replace the old motor.

The top end is from a S1 33 rb25DET auto with a powerfc, the R33 loom has shit loads of wires in it in particular the 2 plugs near the computer.

The plug circled is where I'm stuck, I've searched this and other skyline forums but cant seem to find any pin outs for this plug or diagrams for the interior of a R33 GTST. I know most of the wires are probably not needed but I know the speedo signal is in there (and probably more wires needed too). The 240's wiring is frail so it's up for a complete rewire.

A few questions hopefuly someone might be able to answer...

1 Does a powerfc control air con, I'm not using air so will any problems arise?.

2 What else does the powerfc control beside the engine management?

3 Can these other items controlled by the powerfc be turned off?

4 What kind of signal does the rb25det manual speed sensor produce?

5 Does the signal run from the sensor, through the dash speedo then to the ecu?

6 Is the signal multiplied or divided along the circuit?

PS: Using the hand controller
