Need help! Electrical!

[g35ultra1.0]

So heres backstory to try to help a bit. I've had the car for about 3ish months. About a month in my tail-light fuse blew, i didnt think much of it. I replaced the fuse and went on with it. for the last 2 months ive had 0 electrical issues with the car up until about 2 weeks ago. My main headlights stopped working completely. my turn signals and brights still functioned as normal, I was on the way home 2 days ago when my girlfriend informed me my taillights were not on. When i got home i replaced the fuse, but when i turned the brights on my engine bay had smoke coming out of it right around the brake fluid resovoir. I removced the taillight fuse and the issue persistted. Yesterday i had installed a "drift switch", essentially a switch in-line with the power cable for the abs module. It started and drove perfectly fine without issue. I stayed out a little to late, turned my headlights on, and it was smoking extremly bad to the point it was coming in to the car through the vents. I pulled over, disconnected the headlights and tail-lights just so that i could make it home. When i got in the car and attempted to start it, it just cranked and would not turn over until the battery died. I triued to bump start it which did not work. I ended up having it towed home. I found that my IGN CONT & ECCS fuse had blown. I replaced the fuse and it still did not start even after charging the battery. I did research and found that fuse runs Crank/cam pos sensors, ign coils, valve timing control, and my MAF. I checked/tested all of those pieces with a multimeter and they all tested perfectly. I than noticed that everytime i turn the key to the "run" position it not only blows the IGN CONT & ECCS fuse, but also the ABS CONT fuse. I disconnected the abs module completly and pulled the fuse and the issue still persisted. I checked my grounds and their all good, I did find 2 (possibly the same system) sets of wires, ill attach images, that seemed melted/charred but cant find any information online. Any assistance would be greatly appreciated as my cars stuck at the end of my driveway.

Wow, that is a very serious and dangerous electrical problem, and you've done a great job of documenting it. The fact that you've got smoke coming from the engine bay and two fuses that are blowing at the same time is a huge red flag. You should not be driving this car until this is fixed, as you could start a fire.

The fact that the smoke is coming from around the brake fluid reservoir and that the IGN CONT & ECCS and ABS CONT fuses are blowing at the same time is a huge clue. The ABS module and the engine's computer are connected to the same electrical system, and the fact that both fuses are blowing at the same time indicates a dead short or a very serious electrical problem.

Your research is correct. The IGN CONT & ECCS fuse controls a lot of critical engine functions. The fact that it blows when you turn the key means that there is a short in that circuit, and it's preventing the car from starting.

The "drift switch" you installed is also a big part of the problem. While it's a common modification, if it was not installed correctly or if there was a problem with the wiring, it could have caused a short that is now affecting other parts of the electrical system.

The most likely culprit is a damaged wiring harness. The fact that you found melted and charred wires is a huge piece of the puzzle. The smoke you saw was probably a wire with a damaged insulation that was shorting out and overheating. This is a very serious fire hazard.

What you should do is find the exact location of the damaged wiring and see if you can trace it back to the source of the short. The fact that both the ABS and engine fuses are blowing points to a problem with the main wiring harness that connects these two systems. It's also possible that the headlight issue is related. A short in the headlight circuit could be causing the other problems.

This isn't a problem that can be fixed with a simple fuse replacement. You have a serious electrical issue that needs to be diagnosed by a professional. You should have the car towed to a shop that specializes in automotive electrical systems. They can perform a more in depth diagnosis and find the source of the short. It's not worth the risk of starting a fire to try and fix it yourself.
