Anyone know what these 2 plugs route to? The 5 wire and the 2 wire?With the info given above Im sure its all smog related but thats a lot of wires for just the smog system. I want to make sure I dont unplug something needed.

I am very curious as to the answer to this question as well! I have an 86 de-smogged K20 and have had the same struggles with check engine and choke light as you. I am tearing it apart for restoration now and was wondering what that box was for. This thread has helped me a ton! Thanks for posting it!
