Question Mystery connector/harness on '97 Cobra Intake??

While cleaning up the engine bay on my '97 Cobra, I found a connector/wire plug that seems to be out of place(not connected to anything). The wire/harness has two wires going into it. The wires are red and black with a purple stripe. The wire/plug is on the driver side of the intake, directly under the pcv tube (going from driver side valve cober to intake. The wiring comes from the same wire loom containing the fuel injector plugs. I checked and all injectors are plugged. What in the world could this wire/plug go to?? I am assuming it might be some sort of service port but, I have no idea.

Thanks.

I am hoping this connector is just a service port. Car runs fine an the plug has apparently been there for quite some time.

Any ideas appreciated!

Todd,

I really would like to help you out, so I went out to my garage and checked over my 97 Cobra (also triple black vert). I can't find any wires like you describe, or anything that isn't connected to SOMETHING. Sorry.

Thanks for trying Steve. The harness looks almost identical to the ones going on each of the 4 injectors. It has a 2 pin connector. Really confused what it could possibly connect to.

That's a wierd one, those colours don't match anything in the 97 4v PCM schematic. There is a connector near the spot you are describing that has a brown/pink and a red. It's for the EGR vac sol. It wouldn't affect driving too much (maybe a little pinging and/or check engine light)

scottbeer,
I just went outside an looked at my EGR and it has the wires connected to it. I am going to take a few pics and hopefully post them today for clarification.

Thumbs up

Thanks for all your help guys. I went out and looked at the motor again this morning with better lighting, and found where the connector is supposed to go. The two pin connector actually goes to a black, round kind of canister bolted on to the intake at the same spot as the IAC. I have no idea what this is but, the connector connection is broken off and the wire and connector has been dangling around in the engine compartment. Anyone have an idea what this part is??

Thanks.

Sounds like the vacuum solenoid for the EGR. Follow the vacuum lines to be sure.

Yes, it is definitely the solenoid for the EGR. What would be the effects of having this unit not attached/connected for some time. I'm assuming I would not have clean exhaust and my check engine light would be on, which it is.

Hmm. Without EGR recirculating, you probably went pretty lean with all the extra O2.

/me makes mental note to go check connectors.

Didn't you guys read my post? I told you what it was right off the bat and then I told you it won't do ****. It won't make your engine go lean if it's not working.

MAN, don't have to get all excited.

Todd, here is the link for the 97 service manual CD zip, so as long as you have a CD burner, you can make a copy, if you don't, or you need help with figuring out how to, then drop me a PM.(When I am not in school, I live back at home outside of Chapel Hill, towards Pitsboro/64, but closer to Chapel Hill)
