I used that site a lot to figure out which wires I could remove & some other things but I couldnt find a page that had the info I'm looking for on the wires that need to be fused & the fuse sizes. I also searched here for a while with no luck.

Pretty much everything should be fused. most of the Ign Hot are 5 to 20amp fused. but you should check the spec's from the manuals.

But a few of the key ones:
Battery Hot 12+v (orange)
Ign Hot 12+v (Pink)
- coil
- Injectors
- auto Trans
- ODBII Port
Fuel Relay
Fans Relays

Great question....so I have to add on this question of his..Could we just run an inline fuse in the wires that needs to be fused instead of buying a fuse block?

Well you could, but your wiring is going to look like a rats nest, will more than likely be difficult to troubleshoot, problematic and you may not save as much $$ as you think. If you look here they give you a parts list and it's not super expensive. http://www.lt1swap.com/fuseblock_obd2port.html

As for how to wire the circuits bczee pretty much laid it out. If you need a visual refer to the diagram in post #6, https://ls1tech.com/forums/conversio...-relay-no.html . I am doing something similar to this, but I am changing a few things which are unique to my build.

For my setup I went this route. If you want more details you can click on the link in my signature.

What is that thing to the left of the fuse block in the second picture, and what does it do?

That is a power relay module. I am connecting my main power wire to it and it splits it into two fused circuits, one is battery and the other ignition. You can use up to a 70A fuse for each circuit. This will power my fuse panel and I can tap into for other things if needed in the future.
