Alarm Ground Wires

Here come my next question i got most of my wires ran for my alarm. I just have to ground them, but there is quite a few of them so im wondering if i take about a 8awg wire and ground it then ground all the grounds to it would this be all right?? or should i ground them all seperatly????

Thanks yet again

There grounded to a big bolt to my firewall thats above my pedals. Is it okay to ground more then one thing to a the same ground??

Thanks Player69, Youve been alot of help so far!

Do whatever is simpler, neater, and is easy to figure out if you have to go back to make repairs/upgrades.

Remember, if the ground wire is cut, most alarms are useless-----just like all your other wires, try to hide or disguise it----if a smart thief sees one of those big blue crimp-on ring terminals held in by a self-tapping screw, he'll know he can cut that wire and defeat the alarm.

Also, self tapping screws often fall out.  If you can find a factory bolt that is grounded, use that instead.
