Ok, this re-wiring on the rb20det auto is whooping my a$$ and i need help please. On the s14 (95) near to the f3 plug it had this funny little plug with 10 wires to it with the letter H writing on it. can anyone could tell me what is it and where do i connect it to. Also, the other pic is the wiring that connect to the KA lower harness. the brown-wire.....is that for rear o2 sensor? and on the rb ecu(pin 40) intake air quantity output signal wire...i am lost on that ones also...cause i couldnt find the other wire .
