+12 volt supply wires

My alarm has need for four positive +12 volt supply wires (1 for the brain, 2 for the onboard relays in the brain, and 1 for dome light supervision relay).  I know all of these should be fused between the car's 12 volt power wire and the components of the alarm.  My question is, should these wires all be soldered to a single node on the car's power wire with the fuses after the node?  As of now I have wire taps tapping into the power wire at four different locations.  I realize this is probably not the best thing to do.  The reason I ask is that I am going through to solder all connections and remove all my wire taps.  I believe that the numerous problems with my install are because of loose connections.  Especially since certain features are only functional when the brain is placed in a certain position under the dash.

check out the vehicle diagram on this site up to 2000 models to see the power source, usually in the ignition harness.Houston,TX

I know where I can tap into the twelve volts, i was just wondering if it was common practice to have one soldered node with four wires branching from a stripped section of the power wire under the dash.  I am also wondering if a fuse is necessary for each wire.

No problem, as long as your wire of choice can handle the ( total

) extra load.

Fuses are good. It certainly wont hurt having a fuse on each line. Now, not having a fuse on every line, that could hurt.  1.50 $ fuse holder vs. 20, 000 $ vehicle...........

How can I be sure that my 12 volt wire under the dash can handle the total load of the four wires tapped into it.  I thought that this wire was the only option for getting twelve volts of power.  Would I possibly have to branch another wire off the battery terminal?  Is that what you are implying?

Year, make and model? I'd recommend multiple connections instead of one big clump of solder.

Its a Pontiac Firebird 1992.  I currently am using a bunch of tap in connectors on the line.  Should I just solder to each one of these points?

If your unsure, it's better to be safe and run a new wire straight to the battery.Jeff
