what i know is that only 4wires (two pairs) of the cable is active i.e. connected to supply, ground, data. if this is right which pin of the RJ8 is connected to supply, ground and data

rj8 cable

I think you mean RJ-45.
The network uses two pairs of wires and the signals are transmitted/ received differentially. Thus, there is no ground or power, just TD+, TD-, RD+, RD-.
 

Also, gigabit cables use all 8 pins, with 4 differential pairs. Check here for the pinouts:
