Grounding cable and wires

Total noob at this... I'm tryin to install and aftermarket radio in my 90 YJ and I have the harness hooked up but there's also a grounding cable and one other cable that I don't know what it does... after hooking it up and putting the face on, I tried turning it on and it still doesn't work.

try hooking up the ground wire and see if that does the trick. and what color is the other wire you are talking about?

agreed ^

but the blue wire is usually a remote wire that goes to a constant hot. you can always go strait to the fuse box with it as well.

you ground it to any piece of metal you can find thats not in the open, just make sure its a metal to metal contact(no paint or rust on the metal) use a wire brush or sand paper to get paint out of the way or to remove any rust. and if the other wire is blue or blue with a white stripe than that isnt needed unless you have a power antenna or is you are connecting an amp to your radio.

Perfect.
Normally you can find where something else is grounded and piggy back off that ground

^that to. just dont ground it to any of the mounting screws or bolts holding the unit in place. and its important to have metal to metal, if there is any rust or paint in between the connection the speakers may crackle or there might be a loss of radio signal.
