When connecting the 12V DC, can all the 12VDC wires from the viper join together including the one that connects to the 86+87 of the relay to the 12VDC of the BCM. Or the one that goes to the relay has to be connect to a different 12VDC like at the key switch.

Here is the plan to connect all the wires to the 12VDC Battery Cable.

What's the extra relay for? The Viper can directly handle the trucks four ignition wires.

I'm not sure what gauge is the battery cable to the fuse box, but the one from the Viper must be around 20-24 gauge.

When you are talking about the distance from the source and the fuse, can you clarify which of the below is right?

The relay is for the second starter

This is very similar, either a black or white thick wire as your source going to either fusebox or BCM, then you need only use the existing fuses.

It's for a Tacoma but essentially similar provided this isn't a PTS.

That diagram shows 30 and 50 amp fuses. Does it matter if I use 20amp fuse. What is the difference?

Sorry it's supposed to mean battery to OEM fuses to ignition switch.

Take your two reds, 15 and 30 amp fuses, RED / black, RED / white and extra 30 amp fused feed for second starter from the thick feed cable.

You meant

Take the two reds, 15 and 30 amp fuses, RED / black, RED / white and extra wire with a 30 amp fuse that's for the second starter to feed into the thick feed cable (fusebox or BCM).
