Iv done a search and had some interesting reading...
trying to get fuel pump prime from my SR computer through my N12 ignition wiring (n12 relay etc)
the SR20 uses ground signalling
and from what Iv read here, the E15 uses power signaling...
does this mean, I need to make alterations to my fuel pump relay wiring?
on the wiring diagram theres 2 wires (ecu side) fuel tank/pump/relay related
one is signal from the ecu to kick the pump on
and the other is guage and power
Im having a clusterfuck trying to work it out
can anyone help?

The relay for the fuel pump in the ET is +ive side switched stock.
Its the GREEN relay down behind the drivers side relay.
The existing relay pullin wire from the stock ECU is Yellow/Blue
Ground is Black.
Power supply is White/Black. Itss +ive 12v fused and ignition switched supply power for the fuel pump and ECU.
Fuel pump power wire is White/Purple
To make it work on +ive side switch you just connect Yellow/Blue to the SR20 ECU fuel pump pin # *blah*.
The black (ground) wire down at the relay is just cut and connected across to the White/Black wire at the relay.
Dont use scotchlocks or crimp terminals to join up.
Strip back say 10mm of the White/Black insulation with a razor blade a few inches down from the relay, wrap the black wire around it and solder it for a permanent and reliable connection.
Tape it all back up securely and cover in some split black convoluted plastic tubing to make it all neat and tidy.
