I used a vampire tap to connect the blue wire to the bottom right wire on the right most harness as if you were looking at the ecu from where the harness plug in.

I was told C16...i figured C would be the 3rd harness 16 would be the bottom right wire....anyway its a PM6 89 CRX Si.

If splice the blue wire into that my o2 gauge doesnt worka nymore goes the whole way off the charts on the red led(last red led is very dim) and the volts on the snesor check register less than a .1 like .05-.08 for the 2nd input(blue wire)

What the hell is going on?????
