Default ECU pinout question


Ok so i got an eGay obd0 to obd1 and the chucko didnt send the second part of the harness so i am going to have to do it manually. i looked at the pin outs but not REAL sure on it.

and i need 4 wires going to it

o2 ground
o2 12v switch
o2 signal
o2 heater control


Anyone know which 2 pins i use for power and ground for the o2?

Thanks

So i got

a6 = o2 heater control
d14 = o2 signal
a23 = ? PG1 ground Black, Power ground, less than 1V
a25 = ? IGP2 to main relay and to ground Yel/blk, Battery positive from main relay, Battery Voltage with Key on engine on
a26 = ? LG1 gound Blk/red, less than 1V
b1 = ? IGP2 to pin A25 Yel/Blk, Battery positive from Main relay, Battery Voltage with key on engine on
b2 = ? LG2 ground to shields for CYP & TDC Brown/Blk, <1V

I have the diagram, i just dont know which to use for power and ground for the o2 or does it even matter.

The ones i posted as "?" are the possible ones i know of.

So I don't need to run an o2 with the right tune? im on a basemap atm, can i run without one? Im not a pro at tuning yet.
