02 sensor /before cat

Ok so ijust had my other ball joint broke as the driver side broke about a year ago the passanger side finally went. Well before it broke i was getting the same CEL code which was a IAC problem. Well after i got everything fixed i went back in and now the IAC code is mysteriously gone i now have 2 new errors. The first just says that there is a error in sensor 1 bank 1 and the second is a Heater circut malfunction which is what is wrong with the first. Well since it's a pre-cat o2 i decided I'd go ahead and switch it out as it hasn't been changed since i've had the car and it was pretty much rusted on there. After i finally got it out and got a new one which ended up being a cali spec i went back to try and install it and i guess when the guy rebuilt the car he put the wrong plug end on the car side (ECU side). So i had to replace the ecu side, well know it's all in but im still geting CEL code sensor 1 bank 1 and heater circut malfunction. Does anyone know which wire is what? The colors are Black ; Black/White ; White ; Red. I belive Black is ground and i think Red is power. Only reason I'm not sure is the wiring diagram in the Chilton's manual has it set like this.....

Diagram 93156E17 (6-39 Chilton's Galant/Mirage/Dimante book)
Where 1 is _/\/\/\/\_
and 2 is |i|i|i with a arrow through it

D-90 ___ A-56
|B --- ----- |W
| ----------- |
| ----------- |
___ ----- _____
_1_|-----|_2__|
|B --------- |B/W
| -----------|
| -----------|

I don't know if that crude drawing will help, but it says 2 blacks where i only have 1 Black and doesn't list a Red though there is a red going to the top of he rear heated oxygen sensor any help would be nice :) thanks
