What are the relays for??

In majority of the cars on our roads the ECU will switch an earth to a relay not a positive.

Fuel Pump will be switched by the ECU using a negative..

As for the main relay.. Without seeing a diagram I am assuming that it is the main relay that supplies power to the ECU only when the ignition is on. It is usually switched via a positive from an ignition wire.

If the ECU isn't receiving power from the main relay then everything else won't work.

Once again though I have not dealt with g16 wiring before and am only going off a few other engines that I have installed (mainly Nissan Rb, ca, sr and some other ones)
