evening all,

i have all my elctrics wired up at the moment with only the injectors left to wire into an omex loom.
on 2 injectors i have red and blue wires coming out the plug and the other two injectors have yellow and white.

Does anyone know which side is positive or negative? i know i will have to run a balast resistor to make them high impedance.

thanks james

If I remember correct they are run in pairs, they are fed a perminant live and switched to earth by the ECU. mmmmmm will pop to gargae and have a look.

my nissan ones are wired in 1-2 and 3-4 all live and megasquirt switches earth

Right had a look. Our 4age has differnt wire colours but as you look at the engine from the inlet side the right hand pin is the live.

cheers rusty, thats exactaly what i was after.
i knew that they were wired in banks, was thinking it was 1-4 and 2-3 but will check before i wire them in..

for the help heres a few pics of where im at...

Shame i'm not more local would love to come and have a look. Should get on and fix mine first.

Hey all,

here goes,

12v to ballast resistor is black-orange
from ballast resistor to #1 and #2 injectors is Red
from ballast resistor to #3 and #4 injectors is White or Blue

From injector #1 and #2 to ECU (ie Bank 1) is Green
From injector #3 and #4 to ECU (ie bank 2) is Yellow

I assume you have an Omex computer so in the omex loom (omex 500)
bank 1 is brown wire and Bank 2 is white wire.

Just for info, my 16v was wired up original to the factory ECU and had bank one with #1 and #2, and bank 2 with #3 and #4.
But looking at the piccies I realize that the 20v running on omex has bank 1 with #1 and #4 and bank 2 with #2 and #3

why that is I don't know but will try difference now I know this.

Grtz Thomas
