My wife has an 07 Aveo, head gasket went out and i did the repair. I have it all back together but I now have a plug (2 wire light brown and brown) I don't know where it goes to. I also have a flashing hold light so I think the issue maybe related but not sure. The picture is from under the car look striaght up at the alternator, starter and the back side int he intake manafold. in the same leg of the wiring harness is the 4 or 5 wire that goes tot he alternator. Could this wire be what is causing my flashing hold issue? and Either way can anyone tell me where that plugs into?
