I am installing some pigtails for my FIC 2150s
I am confused which wire out of the pigtail, goes to which wire from the harness?

Pigtail - red wire, black wire

Harness -
Injector #1 - orange and red
Injector #2 - white red stripe and red white stripe
Injector #3 - green and red blue stripe
Injector #4 - red and red

 

Harness -
Injector #1 - orange and red
Injector #2 - white red stripe and red white stripe
Injector #3 - green and red blue stripe
Injector #4 - red and red

red /red white/red blue /red are 12v live so connect to red wire
orange /white red /green /red are switched by ecu so go to black wire


inj4 should be red and red black

 

I realized it doesnt matter because when you think about it the coil is just an electromagnet.
So either way it will work.
Thank though!
