Then this will be easy. In the info sub forum there are wiring diagrams for $0D, $0E and your $E6 which are all basically the same. Peck away one wire at a time and it will all make sense.

I was lurking yesterday and came across that exact page lol
So when i remove everything that i dont need/want, the computer will still make the engine function properly?
Ill make an updated list of what i plan to pull and what im keeping.
Whatever you remove physically still has to be removed/disabled properly from the chip and error codes turned off as well.

Now that is where i have no clue about. Ill be messaging you about it for help and such when i get it started if thats ok with you and you feel like training somebody :)
never tuned a car in my life but always wanted to learn how to :)
No need for a PM to learn to tune. This whole site is full of info and answers.

Can i at least ditch the power block for now and feed ignition and direct power to it to make sure the engine is gonna run right beore completely ripping into the harness
and im unsure about f14, the 5v sensor ref.

Ahhhh? No, it needs power all the time in some spots and Ign On when Key on in others or things won't work right. Well it would probably start and run? I don't know, I just do it right...
F14 sends 5 volts out to sensors that they use to output a voltage between 0 and 5 volts.

From what i see, all i need to do is connect
a1, a2, b3, b4 - ground
e15, f15 - toggled battery aka ignition
e16 to battery
then it should all work golden after i take care of fp and relay stuff
the rest is taken care of by the pcm where i dont have to touch a thing.
That does not match what you had in first post. But it does look correct from the $E6 wirng diagram. But there is more! Look down in diagram, there is power that comes in from elsewhere/fuse panel.
Not everything gets power from PCM, actually it usually comes from the other end...
Orange feeds fuel pump relay with power so PCM can turn it on.
Red power to injectors so PCM can ground them to fire.
Pink wire to feed Ignition Coil
Something needs to feed heated O2 sensor.
Something needs to feed tranny... or... you don't have E trans...
There's more. Look over your harness, rule of thumb is, Red and Orange need 12 volt power always. Pink or Pink/Black need 12 volt Ign on.
It takes some planning while studying the wiring diagrams to re-do a harness. Should end up with at least 2 realys, one for fuel pump and one for PCM/Injector power, I run third for heated O2 sensor. Plan fuses!!!
There's tons of common grounds throughout the harness. Usually TBI pulled harness have 2 grounds to engine block. Sometimes grounds change color mid stream! Black, Gray and Gray is used for other things besides ground, Tan? One at a time!!! Watch what you do from stock and where it d=comes from and goes to...
It's no easy or fast job, I've done a lot of these and to make a nice harness is about 10 hours work... maybe 20 first time.

got EVERYTHING all wired......
now my question comes again lol
i wired up the malfunction indicator light...e6
is this like obd2 where it is supposed to turn on upon ign ition then go away at start?
nvm, got it figured out......
gm did the wonderful switched ground trick on me lol
fed the light 12v and now, its perfect :D
pcm is working perfectly...... ran the light, got a/c code, tranny code, and crank position sensor code...... i don't have a crank position sensor so stupid question, am i supposed to or can i bypass this..... also how will it affect the engine running wise?
There is no Crank Position sensor or code? What ADX file are you using?

i haven't even gone into any of that stuff yet cause i have no idea what it does and what to do with that so i haven't even started to research yet
im getting codes: 59, 67, 82
i gathered readings from these websites and they both came up with different errors....

so i am HOPING it is the transmission giving me all of this shit.
i wired in the computer via

and the pinouts i posted earlier.... extremely similar.
