I am putting everything together and Im testing everything and I realize i have extra things to plug... im confused. I bought this car on ebay and its clear it was someones n02 car. I first bought a ls6 intake and was installing that.. then realized the previous owner already did that. I shoulda checked the numbers on the side before i ordered it. Now i have 2 ls6 intakes and have now bought the 102 fast intake and TB to install. Anyway PM if you want to buy the to ls6 intakes later... My problem is on the driver side were you plug in the small gas line and plug in that orange blue sensor on the same side of wiring harness there is a smaller yellow plug in close to it. i cannot find anywhere to plug it in... i have watched videos on install and i don't see them unplug it from anywhere is this an upper o2 sensor? does it plug in somewhere on the coil packs? Also.. i reach all the way in the back and i have a black rubber hose just hanging there.... unplug from something. its not the breakbooster i have that plug in again. Its crazy how much work has been done to this car... someone put ls6 valley cover on it as well, the crossover coolant line has been changed. Can anyone idientify with what im talking about? why would there be a almost 1 inch black rubber hose with no where to plug in and that small wire.
