For one, maybe two device, yeah. If you are wiring that many devices, though, no I wouldn't. I would run them through the fuse box or run a fused line direct to the battery. I guess you could use the same line assuming everything is fused, but I have a feeling you are gonna burn through fuses, because if I remember correctly, the wire was pretty small so it's not gonna power that many things if they draw a lot of current. It really depends on how much each of those things are drawing though. If you hook it all up and your fuses go pop after not too long, you know its not enough power. I however don't even recommend trying it.
