Need to know what this sensor is for??

There is a orange 4 prong sensor that is on the passenger side near the PCM. It is coming off the same harness for the relay fan. What does this connect too? I can't seem to find anything it does. Also there is a small wire next to it for the fuel. What does that connect too?

Please provide year.

Are you sure it is not an 8 wire connector?

There is a small wire nearby for priming the fuel pump. It has no connection.

There is a clickable harness picture on my Tech Page.

Yes I forgot to mention the year. It is a 1994 LT1 Camaro. On your webpage it is sensor C105 near the fan switch. Do you know what that is?

C105 is not a sensor. It is a harness connector. Look at the harness connector faces page on my website for a description of what is in it.

[edit] Sorry, I just realized there is not a listing for 1994. I don't think a 1994 has a C105. You are probably going to have to post a picture and give wire colors or wait for someone with a 1994 to respond.

Shoebox. It is a harness connector. Sorry for the confusion. What does that connect to?

i'm in the garage now, just looked at both a 94 Z engine harness and the body harness, there is no orange 4 pin connector near the pcm, there is a black 8 pin with a orange seal, which connects the engine harness to the front harness, can you take a pic?

Damn camera is not working but that is the one. I am saying 4 pin when it is actually 4 across top and bottom with a orange seal. Where does that connect to? I can't seem to find the other connection.

the mating connector comes from the front harness, over the shock tower from around the batt area, it is the same harness as most of the fuse links at the red junction post

Dave. I just spend 45 minutes out there and I can't find anything that connects to that 8 pin connector. I checked around the battery, down by the headlights and nothing. Unless it is stuck between something there. I did have the motor out and just got it back in and this is the only connection I can't figure out.

Actually the harness is out of a 1994 LT1 firebird and the PCM harness is from the same.

not postive but when I got it he told me it was out of a 94. But I did buy the PCM harness and front harness together so they should all connect in right? Would it make a difference if it was a 95?
