Hi all,
I've been away from rollaclub for a while,
at the moment I am building an AE71 with JDM bigport and JDM fuel tank.
I am stuck with too much confusing information regarding the wiring.
I have a circuit opening relay.
I have one of these http://www.jaycar.com.au/productView.asp?ID=SY4076&CATID=79&form=CAT2&SUBCATID=979#1
And i need to know how to make it all work
Ive grounded the earth wire from the fuel pump in the boot
I also came across this:
White/Black - Wires to to STA - Starter/ECU Start Signal.
White/Red - Wires to EFI Relay - +12v Ignition Switched power (Run through a suitably sized fuse, 10A is usually fine, but depends on your fuel pump).
Green - Wires to engine run signal - "FC" pin on 4AGE ECU.
Black - Wires to body earth - Wire to closest earth point.
Blue/Black - Wire to fuel pump positive - Gives power to your fuel pump.
One guy from 86DC said this:
The efi main relay is just a regular relay. The oem one isn't required unless you want to have it plug into the *e7* standard engine bay fuse/relay box (i know there is a spot for it, but not sure if the wiring is there like an 86 one). All the efi main relay does is give a 12v ignition source and power the ecu, the fuel pump and possibly one or two other items (probably on later model 4a's).
I usually use the black orange wire (coil/igniter power) to trigger a new relay and create a new 12v iginition source (and label it efi main).
Another:
The COR is supposed to draw its power from the EFI main relay (there is no seperate fuel pump fuse).
The EFI main relay will be switched by IGN connected by a 15amp fuse to the battery.
The EFI main relay also powers the ECU and TVIS actuator.
I'm just confused. someone care to help or draw me a diagram to follow?
