I've read more than a few threads and I'm still not sure, so I figured to ask the experts directly.

I am considering running a dedicated 8/10ga power wire and dedicated 8/10ga ground line for the electronic equipment, which includes the car radio, car alarm, cd changer, equalizer, neon and some LEDs.

I figure I can use the original power line for the radio as a trigger for a relay, and have the 10ga go into 85 on the relay, and output on 30.

The question is whether this is a viable option? Should I use heavier gauge? Will there be any effect for running the car alarm wires (it has two wires running to the battery) with the radio wires? I've been pretty uncomfortable with the two car alarm wires running directly to the battery...

Thanks in advance.

Run the alarm off the Ignition harness.

I don't get whats wrong with the original radio wires or if there is any.

I have run dedicated lines before( for remote start system when it wanted 2 20A supplies). If your gonna be putting alot of stuff in the car it might not be a bad idea. i usually find the earth in the car. on the chasis!

85,86 on a relay control the switching

30 should be to power source

87 should be the device you want switched on

all the pends what are you going to do and what kind of car are you doing U use heavy wire. for Amps YOU have to use 4ga or 8ga, for alarm you just use the ignition harnes and if it is for RS maybe you need to go to battery

how own your mind, control your life.

Maybe I'm looking at this wrong, and I think you might be setting me straight.

The gauge of the car alarm wires to the 12v appears to be the same gauge as the ignition wire. I thought it might be a bad idea (generally) to have that sort of power draw from the ignition wire... though, it sounds like that really isn't an issue?

And, right now I have two neon tubes (12"), 4 LEDs, and the aforementioned hardware running from the one radio wire (because it's already relayed of course, and can't leave the neon on while the car is off). There may be two more neon tubes for the back seats, and two-four more LEDs, but not much - I wasn't sure if the stock radio wire could handle all of that, so I thought it best to run a dedicated wire.

Sorry if the second half of this question doesn't fall into car security - I wasn't sure where to post the initial question.

Again, thanks all so far for your replies and thanks in advance for future replies...

Sorry to bump, but for clarification...

It's a Crimestopper CS-2016FM, with remote start. It does require (as far as I can tell) 2 20ga lines.

So, the question remains - I probably could/should run a dedicated line from which I can run the remote start & from a relay the electronic equipment.

More neon is possible, as is an LCD in the horizon.

Thanks again......
