ok so I was working on my brakes lifted the car and notice this wire hanging

it goes connected to this

looks like a ground cable but I dont know were it goes

and then I seen this Black ball under the by the headlights with the hose disconnected but I dont have a clue what is it for

 

#1-oxygen sensor
#2 climate control vacume ball

 

cool thanks a bunch ...where do I connect that loose plug?

 

The smaller white connector looks like the one for your temp sending unit in the driver's side head inbetween cyl #1 & #3.

And you need to reroute that O2 sensor wire right away, you can't have wires running through suspension.

 

Thanks Bro
