So i picked up a 1989 Camaro iroc pretty cheap as a project but i don’t know what i am doing electrical wise. I made a mistake getting it honestly but i won’t let it beat me. As of right now i just need help making sure it has power then i can go from there. So if any of you guys can help i greatly appreciate it. This is how the car seats as of now the guy completely cut the ecm passenger side harness but i read that it is not needed for carburetor. My first question is what wires have to be hooked up to the battery source to see if it has power?

Reason: Got what i needed
I see so much wrong in this picture other than wiring. Hopefully the engine hasn’t been open to the elements . Wrong distributor. I posted a link to c100 pinout on your other post. Hate to say this but with all that’s hacked up looks like a parts car.

thank you but yeah i am replacing all of that i have an engine to go in it ready to go. I just need know does all the wires that is needed from the c100 have to be plugged up or can i just use the fusible links to see if it has power inside the car?
Has all the schematic diagrams with wire colors, connector positions, etc. in it. Has little sections on each subsystem of the car (starting, charging, radio, ignition, headlights, and so on) showing how each one works. Pretty eeeeeeezzzzy to see from there, I need starting, I need charging, I need headlights, I don't need O2 sensor, I don't need injectors, etc., and YOU decide what you want to keep. Instead of showing usu a giant bowl of spaghetti and coming at us with abuncha INTERNET FIX MY CAR FOR ME NOW or I'm going to call you NAMES!!!, try doing a little actual w ... w ... wo ... wor ... [puuuuuuuuukkkkkkkkkkkke] sorry, I just can't bring myself to type out that whole word. I think the 4th letter is a "k" though; but after I got taken out of the orphanage, the people that raised me were very strict about foul 4-letter words, and here 60-some-odd years later, it's hard to overcome that. Whatever that nasty stuff is, once in awhile you just gotta do a little of it yourself instead of DEMANDING in your juvenile ENTITLEMENT that all of us out here do it FOR YOU. In short, GROW THE EFFFF UP and put on your big girl panties, so that they keep the sand out of your vagina.
This should be a place where people can ask questions and get sensible useful answers. Given the MESS the OP has on his hands, there's NO WAY IN HELL anybody out here can tell him hook this wire here, that wire there, cut this one, splice these 2, you don't need this one, add one here, ... NO EFFING WAY. Too bad people getting into this hobby nowadays have so little self-reliance.
Give-em-hell
Wish I didn't have to, but if that's what they need, I won't shy away from it.
Thank for all you guys help i really appreciate it the car has power now and it’s even driving now i don’t know how but you guys are good at what you do thanks a lot. Cheers 😂
I want to apologize to you guys. I worded my concern wrong to you. I know all the wires that are needed to do what I’m trying to do. My only question was can i hook the fusible links power wire to the positive terminal on the battery and get power in the car or do i have to hook the rest of the wires needed in the c100 to get power? I’m not a mechanic or a electrical guy just asking for a little guidance in the right direction.
All the unhooked crap needs to be identified under the hood first. If you apply power to fusiable links and there’s wires that could ground they will start popping fuses or melting wires. But yes once that’s addressed power to fusible links will give fuse box power and ignition switch. Ground to a clean frame point .
there’s a few hots coming off c100 and not sure if your pass through Connector on the passenger side for efi wiring has been stripped out.

ok that’s all i needed to know thanks a lot i am unpinning what i don’t need now.
In the first few years of these cars, the EFI or CC carb harness, was COMPLETELY separate from the car's main harnesses. In some year or other, not sure which but it was uncomfortably near 89, they merged them. C100 (the big one under the brake booster) got bigger and the whole other harness went away. Starting then, and after that, the harnesses for each car/engine/year got MUCH more individualized and less generic. Which makes it REAL hard to say what exactly you need; and that doesn't begin to address what you HAVE, looking at that bowl of multicolored ramen noodles you have there.
Which is why you need the FSM for your car year. They pop up on auction sites and whatnot from time to time. They're not cheeeeep; don't think you're gonna get one for $5 or something (although you might); butt still, even if it costs $200, you'll spend TWICE that in trial and error, trying to figure out what kind of sodomy Skillet visited upon your poor innocent previously unmolested car while butchering it. (Eeeeewwww, necrophilia...) He should probably go to federal pound-me-in-the-a$$ prison for that, butt I guess it's too late to worry about that now.
Wiring really isn't that hard, once you get down to what each one goes to and what it does. Once you get to that point it's all about technique: soldering, heat shrink, tubing, tape, connectors, crimping, and so forth.
Get the FSM for your car. Think of that as First Base. Next, if you wanna score, you need to get to Second Base, right? Start by getting to First, go from there.
Wish I didn't have to, but if that's what they need, I won't shy away from it.
