-5) This completes the circuit between pins 11 (fused live) and 1+9 of the relay. The ECU is now fully powered up, as is the charcoal canister valve.+  ​- ​This completes the circuit between pins 11 (fused live) and 1+9 of the relay.

- +  - A switched live is already present at pin 14, the ecu provides a negative feed during the prime function and cranking/​engine running via the inertia switch to pin 7.  
-1) A switched live is already present at pin 14, the ecu provides a negative feed during the prime function and cranking/​engine running via the inertia switch to pin 7.  +  ​- ​Provided the inertia switch is completing the circuit this completes the connection between the live pins on 8 and 15 to power the fuel pump, coil pack, speedo sender and injectors. (Pins 4,5,6,13 - your mileage may vary on which is which).
