Talked to a guy from PR that has a workshop here and has a good reputation. Unfortunately he is not in the country but over the phone when I told him about the whole OBD2 problem he just asked... "does your CHECK ENGINE LIGHT comes on AT ALL? - answer = no, never ever, probably even if I rip the engine out of the car, it still won't" so he said... "alright, simple, you are not getting any power to that port... its either a missing ground or a missing b+".
So after soldering the pins 4 and 5 to fix the possible bad grounding issue, I'm just missing one of the steps from the threads above mentioned... run a wire directly from the ECU to pin 2 or crimp the k-line at the back of the BCM connector, which I'm still confuse since there is no pin nor cable on the 20th slot. wtf
