got this ca harness that came with the engine i got a while back and finally got around to piecing it together and when i got to the harness it seems really weird at the ecu plug has quite a few wires hanging out of the ecu plug that seem cut off , i assume it should go to the f1 plug thats not there.. any help on how to wire in.. i have a spare ka harness i could get it off of

also before the ecu plug theres a white plug which i think should be the f3 plug but it only has one wire pinned into the plug and i dont see any cut off wires that may have been taken out of the f3 plug...

the rest of the harness seems to be on point ... just want all my stuff to work right so any help would be awsome thanx!
