New page

The C101 plug is the biggest connector on the vehicle [[Loom]]. It allows the entire engine wiring to be disconnected from the rest of the vehicle, so that the engine can be removed easily.

It is located on the bulkhead in the engine bay, next to the [[Brakes#Brake_Servo|brake servo]].

		+	'''WARNING:''' There is one difference in the C101 design between the E30s, and that is Pin 20. On early vehicles, Pin 20 is a brown earth wire, while for some later vehicles Pin 20 is a live, unfused red/yellow wire for the [[Brakes#ABS\|ABS]] system. If you are changing your engine, '''CHECK PIN 20 ON BOTH SIDES OF THE C101 PLUG''' before connecting the battery.
		+
		+	If you have a brown wire connected, cut it away from the pin, and make sure the free end can't come into contact with anything. If it is red/yellow, then leave it alone. Of course, if the body side of your C101 has a red/yellow wire on pin 20, and your new engine loom has nothing connected to this pin, you need to add a wire, capable of carrying about 15A, from either of the terminals marked '87' on the DME relay socket to pin 20 of the the C101 plug, otherwise your ABS braking system won't work.
