Ka plug identification please help!

Guys I'm swapping back in a ka into my car and when I had the SR it had a white plug (f4 I believe??) Plugged in. The used ka harness doesn't have this white plug. Is perhaps my ka harness just screwed up? Thanks for the help guys http://uploads.tapatalk-cdn.com/20170106/70cde32833fbb93547806209047685e5.jpg

The location of this plug is located on the passenger side footwell where the stock ECU would go. I'm assuming it trails to the back of the car where the tails and fuel pump wiring would be

Your photo does not show any KA engine harness present at all. Have you routed it in through the firewall? Your photo shows the M63 chassis plug (which the large, white F3 plug will connect to) and two other chassis plugs. Your F3 plug may have gotten stuck behind the HVAC unit as you fed the wire harness in through the firewall.

Yes. I'm showing the chassis side. But the ka harness I have does not have the f3 plug. That's what I'm trying to figure out. Do I need the f3 plug on the ka harness ? Thanks if that makes sense. And I have not routed it through the firewall as I want to make sure that I do indeed need that white f3 plug your referring too.
