Engine harness plugs question

[Mr. Y]

Hello guys.
I can't understand where plugs #1 and #2 go.. They're on engine harness side (88+)

See attached picture and thanks for help in advance!

#2 looks like the other igniter plug
edit: never mind, looks like you have two already labeled igniter plug
edit2: so it looks like it could be C1 - a joining connector for harnesses

thank you... I'm installing new engine harness on friend's car and it's strange... ECU plugs are 89+, but chassis side is pre 88 (like on my own car)... Looks like I'm going to have some soldering job...
