So after checking the signal wire at the starter I realized it was getting .34v. I tried my old ignition switch that came factory on the car and started right up. The one I had on there I bought from stm a year ago and it went bad already wtf?

that's unusual for a replacement to go bad, it is a super common problem though. That's great at least you got that figured out. Electrical gremlins can be such a pita.

Just to chime in before you say your ignition switch is bad, I wanted to ask if you're aware of the rotational issue they have? Sometimes they move juuust slightly when you turn the key and the key isn't able to turn enough and cause it all to make contact. This wouldn't be a bad switch, but the switch might not be affixed properly.
I also wanted to mention that I've had reeealllly strange electrical problems with ground issues (in fact, when I did my clutch, my intake manifold ground wire pulled out of one of the lugs and when driving in the rain one day it melted a good portion of my harness which caused all sorts of haywire). If the car is losing charge over 2 days or 2 weeks, you have a grounding issue somewhere for sure.
I used to hate electrics... but some deep breaths and focus on less than intuitive details will get you to the problem.
Also, keep that battery disconnected while parked in case something strange happens and it wants to self immolate.

Thx man yeah i have the battery disconnected and def going to check all the grounds. I oredered the evo x junction box but i have to figure out how the hell to hook this all up. I bought all the wiring as well. Best thing would be to redo the whole battery relocation since they did a crap job. Im aware of the ignition switch issue. I actually tried to hold it in place to make sure it doesnt move while turning the key. I ended up installing my old ignition switch and it turns on every time. Its just hard to tighten that stupid bolt. Im going to try to find one that i can put a socket on it so i get better grip when tightening. Also, now that im messing with it would it be beneficial to use some of the leftover 2 gauge wire and replace some of the current grounds with this wire? Like the one on the intake manifold etc?

You could use that left over 2 gauge to ground the battery to the chassis. You could also re-use some of that aluminum 4 gauge to add engine to chassis grounds.
You have probably seen it, but this is the STM kit https://stmtuned.com/collections/mit...relocation-kit
What I don't know is if the factory cables will bolt straight up or if they need a little modification.

Yeah i just purchased that a couple hours ago. i think that would be the cleanest way just need to figure out which cable goes where since i dont have the factory stuff. Ive been reading a bunch of posts but none are very clear on it. So by adding grounds you mean just add another wire on top of where the current grounds are?
