V1 Another What’s This Connector Post

[Jareth]

As much as I tried to label every connector some were missed or label fell off

I have a few so I will number them as I post them, so if you could help me identify where they go it would be greatly appreciated.

Connector #1, Answer= “Negative Battery Cable”

 

[Jareth]

Connector #2 is a long one that was combined with wires near the gauge cluster? Answer= “Ambient Light Sensor”

.

 

[Jareth]

I know here this large one goes.

But the following two I need help with they come out of the harness with the above transmission connector.

Connector #3 Answer= “This one goes to “Knock Sensor”

Connector #4 wire colors = “Light Green”, “Purple “ and “Yellow”

.

Connector 1 looks to be the current sensor on the negative battery cable.
Connector 2 looks like the ambient light sensor

One of the other two might be for the ac compressor but that doesn't look like the right part of the harness for it.

What color wires do those connectors have?

 

[Jareth]

Connector 1 looks to be the current sensor on the negative battery cable.
Connector 2 looks like the ambient light sensor

Thanks,
#1 does connect to negative battery

If #2 is ambient light sensor where dose it connect to?

It's a small dome shaped sensor that you remove from the dash when stripping the donor. Here's a picture.

If you didn't save it, they are cheap and should be available.

 

[Jareth]

Oh, that small domed sensor that I obviously threw out

Thanks for part number have one being shipped out.

Connector #4 wire colors “Light Green”, “Purple” and “Yellow”

 

[Jareth]

Red Connector #5 should be obvious but I don’t see any place for it to plug in? I’ll have to take a closer look, seems heavy duty so is it a power connector between engine harness and main harness?

 

[k.rollin]

The red one looks like the radiator fan connector.

 

[Jareth]

Thanks, based on your reply I confirmed it by searching on “Cobalt Fan Connector” and found a photo that matches

 

[Jareth]

I think I have all the connectors solved except for this one?

wire colors = “Light Green”, “Purple “ and “Yellow”

Missing piece to the puzzle is that I figured out based on my stickers “006” that it had this short adapter cable .

with these connectors on it.

Is it to the AC Compressor?

I'll try and remember to dig through the service manual when I get home this evening to get you the answer, if no one answers before. I'm thinking it might be a wheel speed sensor since they had some short adaptor cables.

Edit: So not a Wheel speed connector. Based upon a picture I posted in another discussion, the wheel speed was only 2 wires.

 

[Jareth]

Found this image and #12 is a short cable for the “Crank Shaft Sensor” that looking up from underneath is hidden in corner above starter near Oil pressure sensor.

 

[Gtstorey]

That's probably it. There aren't many adaptor harnesses for the engine.

 

[Jareth]

Has to be I have one cable left and one empty connector, only issue I need to wait for my wife to get home to plug it in. I’m not able to squeeze my big hands in there to connect it.

.

 

[Gtstorey]

Manual confirms the adapter harness is engine harness to crankshaft position sensor.

 

[Jareth]

Thanks, I appreciate your help

So just found another connector that I’m not sure where it plugs into? It is in the harness near the BCM?

That looks like the TPMS/ keyless receiver plug.
