Ok, i will give the jumpers, it's from a WREN III HH disk drive Manual
Model 94211 (SCSI):

	The Termination Resistors are SIP Modules plugged into SIP
	sockets on the Main PWA, accessable through a hole in the PWA
	behind the DC power cable connector.

	                       ----------------
                              |               |
	 ----------------------  4  2  1   P  |
	| B T  A  *  T  G  M  |               |
	 -------------------------------------

	 P is the Parity Jumper.
	 4,2,1 are the SCSI-Id Jumpers

	 Jumper between M-G enables Motor Start option, drive wait
	 until host adapter starts the Motor, no jumper drive spin
	 up as soon as power is applied.

	 Jumper between T-G means Test seek option, no normal operation.

	 Jumper between A-T means terminator power from WREN III power
	 connector, B-T means terminator power from SCSI cable, pin 26.

	 If unit is not to be terminated, remove the terminator packs.
	 Removal of terminator power source select jumper does not !!!
	 disconnect the terminator resistors from the circuit.

	 Happy Playing, don't loose the jumpers :-)
