ECU help

does anyone have a "map" for the wiring on the ECU? i was hoping to hook up an air fuel gauge this week and i need to find the O2 wire that runs though the harness and to the ECU, my friend wired his under the hood but it looks quite tacky and amateurish.

any help would be greatly appriciated,

and yes, i tried searching i t, and came up with nothing...

Honda-Tech.com: Honda CRX / EF Civic: D.I.Y. / FAQ - OBD-0 --> OBD-1 Pinouts and Conversion Help

This thread has the wiring pinouts for converting obd0 --> obd1.
According to the list, the obd0 ECU pin for the o2 sensor should be C16 (02S) if i read the chart correctly. Hope that helps.
I dont remember if the pins on the ECU are labeled with letters/numbers so i'll try to find a picture later to show which pin is C16 if you arent sure.

look at the picture below, this is off g2nick's post....the middle chart is the only dseries on here, and it says c16 is the o2 sensor wire, is that correct, this will pretty much match up for my pm6 ecu?
