Okay so im really close to finishing my sr20det swap into my s13.

I just found out that i am not getting ENOUGH power to my coilpacks, its reading like 1v of power..

So i traced that red and blue wire all throughout the engine harness and turns out it goes right into that big plug behind the battery that plugs into the body harness.

What is weird is that on the body harness plug side, the medium sized red/blue coilpack power wire connects to a green/yellow small wire and i have no clue where that goes.

Question is, how do the coilpacks get power? Im sure it connects to some sort of 12v power wire but right now it just ends up to that plug behind the battery.

Im thinking my body wiring harness is fucked some way or another

Any wiring gurus out there that can help with my problem?
