Narrow Band Signal for FI

[microsa1]

I have a SM-AFR that I bought new a few months back and want to use it on an 1984 BMW E30 W/an M10 engine. I have a new W/B O2 and harness that will be used with the system but the F/I system on the car (Bosch L-Jet) uses an input from a narrow band O2. Is there an output on this system's harness that I can use for the ECU or will I need to add a second O2 bong to the exhaust.
Thanks

Yes, there is a 0-1V narrowband output on the SM-AFR.
