no pictures?

the green/black and yellow are probably for the back-up light switch on the transmission - if the white is right next to the green/black and yellow, it would be O2 sensor

 

the plugs in the bottom picture - white plug connects to chassis harness at driver's side at firewall - green plug goes to injector resistor box

 

so the white plug is somewhere inside the cabin on the drivers side by the firewall. i thought the black wire went to the o2 sensor

huh, well i pulled all my wiring through the firewall so i gotta find that plug. so what is the black wire for?

 

whats on the end of it?

 

i think its just cut but ill check it when i get home

 

peel back the harness covering a ways and see where the black goes - the O2 sensor wire is shielded and the ground for the shield is a black wire - could be

 

well i cant find that plug thats supposed to be on the drivers side, where do the wires for that plug go?

 

to the ECU
