Headlight dim, where is ground cable?
 

Hi all,

I am brand new to Scion tC, and brand new to this forum. I have a 2009 Scion tC automatic.
The headlights are not as bright as it should be. I already restored the headlight lenses (crystal clear now). I looked for headlight dim solutions and found that corrosion in the ground cable might cause this problem.
Can someone help me to identify where is the ground cable and possible how to change that?

Thanks a lot.
