MM30SR Wiring Diagrams

These following drawings are my attempts to draw up what exists on my MM30SR.  I've done them to help me understand how the wiring works and to help if I have a fault.  I've done them as accurately as I can but....

There are 5 relays below the seat.  Starting from the cab door side these are:  

Please be aware these relays are easy to remove and if two or more are remove together there locations might be swapped around. Best check the wiring colours.  

Start Relay.  Has large pink/red and white wires together with smaller 2x green and yellow.

Glow Plug Relay.  Has large orange and yellow wires together with smaller orange, yellow, purple and black (red stripe) wires 

Hydraulic Valve Control Relay.  Has orange, yellow and 3x black wires.

Safety Start Relay . Has 3x green, 2x yellow and 2x black wires

Glow Plug Timer.  Sits above the 4th relay and has 2x purple, green, black (red stripe)  and 2x black wires

The drawings below cover all these relays.
