Try not to criticize me too much I mad a bad decision while trying to install an aftermarket head unit. I couldn't find the adapter for the old head unit to the new one so I just cut the old plug thinking I could hard wire it now I have no idea what I am doing. I got all the speakers hooked up right from random forums but can't find what to do with the rest.

 

I have multiple wires of the exact same color so diagrams are starting to get me frustrated

 

What year and model monte do you have? That will be needed for anyone here to assist.
