31b is white/red-tach signal from coil. when car stalls, this opens the relay, stopping pumps.

31 is black wire-ground for the relay. in the turbo, if the boost is too high, the switch opens and removes the ground.

15 is blue/red wire-power to the relay from the ignition switch.

87 is yellow/red-power to the pumps.

87b is blue-power for the lambda relay and the control pressure regulator heater circuit.

30 is red-power for the pumps when the relay is closed.

off hand, i'd say the relay is heating up from too much current draw. they WILL get warm under normal operation. how hot is hard to judge from here. good luck, chuck.
