7730 Pin-out

Does anyone have a Pin-out for a 7730 ECM and its corilation to the circuit board. I have a EBL P4 and someone already hardwired ADC channel #1, but I don't know what pin it is hooked to. I'm trying to hook up a WB 02 and want to know if I can use that pin or if I need to run another channel. Thanks in advance if anyone can give me some insight on this. Also I'm attaching a pic just in case I did not explain that very well. The white wire I circled comes From the ADC Channel #1.

That wire appears to be on pin E1.
