Well 1 green and 1 green/red

Here is a pic of the 2 relays I have tried 1 original and 1 brand new they both prime the pump for 2-3 seconds

and here is a replacement speed sensing module its has 113 last 3 digits of bosch number mine had 116 last 3 digits

Speed sensing module pin outlays

31 = earth (shared with fuel relay below)
15 = switched live
88a = over run shut off valve
31b = thermal time switch
31e = cold start valve
1 = coil negative from coil supressor

Fuel pump relay pin

1 = coil/rpm instrument panel
15 = switched live
87 = fuel pump
30 = permanent live
31 = earth (shared with speed sensing relay)

The safety module is located under the facia panel on the driver’s side and is coloured purple (see illustration).
Its purpose is to shut off the power supply to the fuel pump should the engine stall or the vehicle be involved in an accident. The module senses ignition pulses, and cuts the fuel supply if the ignition pulses stop.
The fuel shut-off valve system is an economy device whereby air is drawn from within the air cleaner unit through the shut-off
valve and directed into the ducting chamber above the air sensor plate causing a depression. This then causes the sensor plate to drop which, in turn, shuts off the fuel supply.

The valve is operated by signals from a coolant temperature sensor and a throttle position sensor. The shut-off valve will only operate under the following circumstances:
a) When the engine coolant temperature is
at or above 35°C (95°F)
b) When the throttle is closed and with the
engine speed decelerating from speeds
above 1600 rpm

The engine speed is sensed by a speed
sensing module which is coloured black and
located beneath the facia panel on the driver’s
side
