man when i first made this thread i was hoping it wouldnt have turned out like this...i had everything all space out and now its all bunched up and looks like sliced a**...SORRY GUYS!!!

[godzilla_753]

a single tear just rolled down my face

haha MAN I HAVE BEEN LOOKING EVERYWHERE!
ill take this and make it into a nice little diagram for easier reading. really appreciate it man, i am literally starting the wiring on my NEO swap today and this is a godsend.

[godzilla_753]

ill one up that!
check it !
