grounding wires?

I got some driving lights, and to set it up, I need to ground 4 wires. Some of the spots are close quarters, so I was wondering 2 things:

1) can I ground more than one wire to the same spot?

2) can I ground the wire some other way than using a screw? Like superglue or something?

Sounds pretty novice, I'm sure but I don't want to mess these up. Thanks :)

You can ground more than one wire to the same spot, and super glue won't hold it. :D

thanks, you know of anything that will hold it?

screws, just use them under something where they wont be visible, run wire from then and ground it somewhere else

thanks, you know of anything that will hold it?
Duct Tape. A.K.A. "Cowboy Chrome" If you cant Duc' it, fuck it.
Also, make sure your grounding to a bare piece of metal. its not hard, if you have to, drill a small hole somewhere in your engine bay and use self-tapping screws, but im sure there are a couple random nuts you can tap the wires into.

hey thanks guys. I took robo's idea and spliced more wire onto it and extended it to a place I could drill a hole ito with those selftapping screws. All works now thanks again :)
