The connector isnt connected to anything its on the back side of my engine close to the firewall. Its very close to where the break line booster hose is. And the other picture is my repaired break line booster hose i was wondering if this could be a reason my car wont cut on sometimes?

It may be the brake pad wear sensor, see if there is a harness with a wire coming off the inside of the brake caliper.

That looks like a temp valve connector. look for a electrical plug on the block or intake manifold that has two prongs on it, near the driver's side valve cove.
Brake pad sensor wire connectors tend to be of the round variety.

That brake booster line fix is dodgy at best. You need to buy a new brake booster line, if it fails again you are back to very hard brake pedal and it may go at the worst time, braking in heavy traffic. They are about 40 bucks from AutohauzAZ.

That is a theremo valve, either 50 degree or 70 degree, not sure which on your car. It has to do with the cold start valve or idle control.

Last picture is not a factory wire loom collection. Looks DIY to gather loose wires.

Thanx for the info. I actually am currently having a issue with the car not starting from time to time and u said that the picture of the connector has something to do with my cold start valve. i recently posted another thread about how my cold start valve electrical connector (il post another picture in this thread) was damaged and i open the wires taped them because bare wires was touching. Also another problem im currently exp experiencing is i can take the electrical wire going to my ICV off and no change. It seems to be all connected in theory but im not good with cars so i dont know. I tested the wires to im ICV with a light tester and no light what should i do next?
