This isn't in a cossie but the idea should be the same?
Bit confussed about the earth part
I'm wireing in a pump via a relay and the instructions below I have from another site read as if the earth is via the ecu and not to the battery/ground ?
"The fuel pump signal wire you will be using for the ground on your fuel pump relay, this way the ecu has control of the fuel pump and will shut the pump off if the engine is not rotating, a good safety feature"
