Edit - Can you make the connections at the relay clearer? I am not sure what A,B,C,D,E means. Specific names like Ground, Relay Coil +ve etc would help.

Let me try and guess -

E - Coil +ve
D - Coil GND

B - Common
A - NC (Normally Closed)
C - NO (Normally Open)


And why not use a diode in place of the relay? It would have a much simpler 2 wire connection. Does it cause any problem with the BCU?
