Well, that can't be too tough. The 30 is a blu-red wire right from the battery, the out is a blue wire right to the blower and the 1 is the ground or control side of the relay. The Motronic control unit will ground the blue-pink lead at terminal one, this will close the relay and current will flow right from the battery,, through the relay, through the motor and to ground. With the two big wires hooked up you should be able to run a ground to the pole for the little wire and the relay should close.
