Working on my wiring harness I have a couple of questions. I have now pretty much figured out the harness. I have routed everything mocked it up and pretty much deleted everything I don't need on the 99 camaro harness. I have removed my TPI harness and have all the wires i will be connecting to the 99 PCM separated.
Right now I have a few questions.
I have 6 Ignition 12V common wires left.
2 go to left and right Coils/Injectors can I safely hook these up to my old 15AMP inj1 and inj2 circuits.
The rest go to:
2 to right and left 02.. I deleted the rear
1 to transmission connector
1 to MAF sensor
Do anyone know what size circuit/fuse i will need to hook these up to?
What kind loom/harness tape do you guys recommend.Im using pretty good quality tape just to hold it together for now. I found some braided stuff that Jegs offers at a good price. What do you think?

I found pretty much all the info I needed In a post by Pocket.
Thanks Pocket

MAF is up to you if you want to go SD or not. IAT is required for any engine
Next, you dont want HO2s to have 12v constant. They will kill your battery in a few hours, give them switched
Join the ALDL, PCM 12v constant and fuel pump relay 12v into the same fuse unless your pump has an excessive draw, IE A100, aero340, Bosche 44 etc. Walbros are just fine being on the same fuse
No point in running a separate fuse for the IGN relay trigger
This is the schematic I drew when building a stand alone. Maybe it will help you sort out the needs vs dont need
This is my minimal LSx harness using an 0411 PCM pinout. I drew it a long time ago so the fuse ratings arent current, but the basic shape of the harness, whats needed etc are still correct

The pcm battery fuse only needs to be 10 amp. I think the MAF fuse will need to be 25 amp. Here is a link to the f-body schematics, so you can double check this.
