Ok I had an engine fire awhile back and I'm just now gettin to the point where things are starting to be put back together (I think). But I need some help. Here's the story:

Green Arrow: Dont have a clue where this attaches. Its bolted to the block so its a ground of some sort, but I can't seem to find where it plugs into (also the insulation is melted so I'll have to craft up another wire).

Orange: Some plug of some sort thats hanging off where the two lower injector plugs split off. Again, dont have a clue where this is supposed to go. My old wiring harness was too toasted to even recognise so I can't look at that one for reference.

Purple: Some sort of sensor on the exhaust. Ive got an extra wire coming off where the lower injector plugs split of that I'm thinking connects here, but I'm not sure since the plugs got melted in the fire. Am I correct? Does that extra plug I have at the lower injector split connect here?

If you need me to take different pictures let me know.





Thanks for your help in advance.

 

Green arrow. Connects to Spade lug just to the leaf of the windshield wiper.

 

Here is a good layout of the Emissions harness:

The orange appears to be the Water Thermo Sensor Connector

 

Purple is your Oxygen Sensor

Hailers Please feel free to jump in!!!!!!

 

ok purple is the oxygen sensor, but where does it plug into the harness? or does it?

 

I think they have already been ID'd. I got three out of three wrong when I looked. The purple....I see where you put a purple arrow on the o2 sensor and then a purple arrow on the connector to the o2 sensor....but as I follow the wire from the connector I can't see if the wire is a part of the harness or just broken.

The orange....its just headed the wrong direciton. Should be going fwd as Banzi said. Goes to the sensor on the back of the water pump housing.I think I can see the sensor that it goes to in your picture. Its sort of green in color.

And I see that *hideous* thing that is orange in color with a valve core cap on it. Rid your self of that thing. Begone hideous thing.

 

ok. heh, the wires I didnt claim to be in the correct place . Theyre just there cuz that's where they fell. Anyway. The O2 sensor wire was melted in the fire so the one in the pic is broken and I dont know where it is suppoesed to connect. I am going to have to repair the wire, but first need to know where its supposed to go. The Orange arrow goes to the water pump? We'll I removed the pump entirely because since I bought the car, it hasnt been hooked up and was rust locked. So I guess the water pump connector is useless to me now. Ive figured out where the green arrow goes, just need to repair the wire as well. So now I guess all I need to know is where the O2 sensor is supposed to connect? Is there a connector on the wiring harness that it is supposed to plug into?

Hailers, what are you talking about this *hideous* thing that is orange in color with a valve core cap on it?

the o2 sensor connects to a single prong plug that's coming off a wiring harness that connects to the injectors, water temp sensor, and ground (below intake on top of engine)

I am sure you could get better info looking at the FSM

ok great, thats what I needed to know. its hard to see in the pic but that connector youre talking about is right there. I just wasnt sure if that was the one that goes to the o2 sensor or if it was supposed to connect somewhere else. thanks for the help guys. i think ive got it all figured out for now!

 

yeah, on the 1st pic, I see the o2 connector a tad to the right of your redish arrow (behind the water thermo sensor connector wire)
