    I put a d16z6 into a 93 sedan civic, and the engine is throwing map sensor codes, o2 sensor codes and a bunch of others. The car was not pre wired so I ran wires for the vtec. Any was the when I use the 1.6L map sensor the cars idle bounces between 1500-2500. I have to use the 1.5L mapsensor which is on th ecars body and the idle is constant but really high.

    I found out this is happening becuase theres three more wires the cars bodies harness is missing which are right by the vtec wires,
    its missing pinout D21 -SG1 D17 Map( explains why) and D19- VCC1

    My question what do the D21 SG1 and D19 VCC1 stand for, and also should I expectg to find other wires that aren't pre wired for installing a d16z6 ina 93 sedan.

    All three of those are for you MAP sensor.

    What 93 Sedan?, not that it really matters, it shouldn't be missing those wires anyway.

    MAP - YEL/RED --|| -- YEL/GRN -- ECU at D19
    """ - WHT -------|| -- PNK/WHT -- ECU at D17
    """ - GRN/WHT --|| -- GRN/BLU -- ECU at D21

    || indicates the engine bay canon plug.

    There's no way they are missing. It's not a special sensor that changed based on model, maybe you're looking at it backwards.

    yah its totally missing all those wires, thought it was weird cuz I put this motor ina 94 HB and it had all tose wires but noo vtec wires. noticed today when I looked at a civic with a sohc vtec.

    its a base model sedan..........only option it has is tilt sterring wheel and power steering.

    no I can send u a pic if you want, the top of that plug from the body harness has no wires coming out, it has the vtec wires now , but not those other 3.
    Should it have those plugs to be running a 1.5 L. this is weird.
