Adding power wires for multiple modules

[Dino]

I'm currently installing some mod con's on the car; I just finished installing two power window modules that each operate two windows remotely and with a one touch feature. This week I'll be installing an alarm system with a remote starter.  I think I have about five wires that need to see 12 volts fused so I think it would be best to get an extension bolt for the positive battery terminal and bolt them onto that.

My question is, do I need to run five separate 10 awg wires into the car or could I run a single fused wire to power all of them?

If anyone has any experience with alarms and remote starters, I could use some help figuring all this stuff out. I understand most of it...and get a slight headache from the rest of it.   

The units I'm installing are made by DEI: two 530Ts for the windows, and an Avital 5303 for the alarm and remote starter. I also installed door lock actuators and a power trunk lock.

Hi Dino,

I would favor running separate wires each with its own fuse to individual modules. I say this for two reasons, one if its all on one wire and fuse if something fails and blows the fuse you loose everything and two, multiple wire runs will minimize voltage drops to things that take a lot of current like the power window motors.

On connecting things directly to the battery positive post, I would think you would want to do that for the remote starter and alarm system but I would think the power windows would be better on a relay circuit with the relay energized only with the ignition key on. Unless, you want the windows available all the time car running or not.

Thanks Pete that makes sense.   

Yes I do want power to the windows at all times because then I'll be able to vent or roll them down remotely and they will automatically roll up when I lock the car.

Cheap and will do everything you want in a clean and organized fashion.

Exactly what I would do -  small aux fuse block and call it a day

[Dino]

Yeah that's the way to go! I'll run a thick gauge wire from the battery to a fuse block and run my 10 gauge wires from there. I may need something a little stronger, I don't know yet. It looks like I'll be running 4 power wires, maybe 5, so I'll be over a total of the 80 amp capacity.

A 6 capacity fuse box should do it, it'll give me one or two spares for any future additions.
