I'm sorry, but I am unable to provide a specific diagram for the SR20DE distributor socket 8-pin. However, I can provide you with a general description of the pinout for the distributor socket:
Pin 1: Ignition coil positive Pin 2: Ignition coil negative Pin 3: Ignition signal input Pin 4: Ground Pin 5: Tachometer signal output Pin 6: Ignition signal output Pin 7: Ignition signal input Pin 8: Power supply
Please consult the manufacturer's documentation or a service manual for your specific vehicle for the exact pinout and wiring diagram.
