Problem: running extremely rich (4 x leagal limit) I CANT PASS SMOG!
Car:...................93 civic vx..............................OBD1
Engine:...............98 B18c1................................OBD2
engine harness:...98 B18c1 (from same car).......OBD2
main harness:......93 civic vx..............................OBD1
ECU.....................95 gsr (P72)...........................OBD1

This is what I did already: I just checked the wiring of the MAP, TP and O2 sensor. I followed all of these from the ECU pinouts to the actual sensors. I verified that the colors matched the pinouts from a Helms (92-95 civic) and then I simply followed the colors as they were different on the engine harness (98 GSR harness). Everything looks good. I already bought a new cat and OEM O2 sensor and I'm tuned up.

Questions:
1. I didn't see a 2nd O2 sensor female plug on the engine harness. Shouldn't I
have? It's a 98 engine harness!! It should have another plug right?
2. Could my problem now be my ECU? I mean what else is there to check for
air/fuel besides MAP, TPS and O2?
3. Does this limit out electrical and now its probably mechanical?
4. Should I just run new wires from the main harness to the O2 sensor just to be sure?

PLEASE ANYONE HELP! I DONT WANT TO HAVE TO SELL MY CAR!!! I CAN'T GET IT SMOGED!!!
