Wiring help

[anaphe]

Hi gang,

I have help id'ing the 2 front 02 sensors ( I know 2 of the plugs are keyed) but how do I ID the front plugs?

Also I have 2 plugs on the exhaust side of the engine ( One is the coolant temp on the lower rad hose) but not sure what the other is.

One is gray and gray/blue and the other is green/white and blue / yellow.

Thanks for any help ! With spaghetti coder gone I am lost!

The green/white and blue/yellow wires are for the rear back-up light switch on the transmission.
