Can somebody please help me identify what these harnesses / plugs are for? Also, what would be the best way to connect the fuel line that's rigged in the last picture?


This is under the steering wheel. This looks like it should plug in next to the VSC button, but there is no button for it. The spot that should have a button for it, is a blank.


This is under the passenger side dash board. Im trying to identify the connector thats taped off. Airbag?


Lastly, this looks like it goes to the starter. However, about mid way through the harness, there appears to be a retainer or bracket that is supposed to be attached to something. Can anybody help me out and tell me what its suppose to be attached to? Also, the fuel line is super ghetto rigged. How can I properly attach it?

Thanks for all the help!
