Power supply wires 4 304 harnes

Post by Humptydumpty »

Can anyone confirm this is the correct Wirring to power up the ecu and system On a Vn ecu and Wirring loom.

- Purple/violet wire goes to pin 30 on relay (plus a positive supply wire to fuel pump from this same pin)

- relay pin 85 gets the green with white trace wire (this should be the wire that switches on relay wen ignition on) this is on a timer wen ignition is first turned on to start fuel pump?) not getting anything from this wire.



- relay pin 87 gets orange wire from oil pressure switch - the other side of oil pressure switch is direct to battery +(switches relay on once oil pressure is up) goes to relay pin 87

- relay pin 86 to body earth?


What am I missing? The red with black trace is getting a constant 12v from battery - the red wire is getting power from 2nd relay which is switching on and supplying power wen ignition is on. Earths are grounded. Igniter box is connected, dizzy is connected, coil is connected n injectors all plunges in etc....
