C101 is the big connector NEXT to the fusebox in your car.

The plug in your pic. is the C101. The other big round one is the diagnostic socket.
As said above, it plugs in right beside the fusebox, and the loom from its socket goes to the fusebox, BUT, nearly all the wires (fuel pump is the exception) just pass straight through the fusebox and out into the cabin without connecting to anything inside the fusebox.
If your car doesn't have a 20 pin socket to suit this plug, then you probably have an early version of your body loom which had a rectangular socket with many less pins, plus a three pin socket under the dash for a couple of functions.

i just check my car inside a plastic cover, yes I found a big round connector in side of my fusebox i think this c101 should attach to this.

my car is 1991 m40

thank you brian, speedtouch, grrrmachine.

All the engine loom connections to the car, except the main loom earth and permanent live go through this plug. Exceptions are connections to the small plugs near the ECU plug, on cars with a switchable auto gearbox and/or aircon.
Your engine loom will have extra wires fitted to the plug compared to the M40 loom. These are for the oil level sensor, which you won't be able to use.
