Disable your stock 02 in hondata and run the white wire to d14 on the obd1 ecu. You may need to play with your gain settings or voltage settings.

P28 w hondata S300

I have the wideband welded into it's own bung so Ihave the 2 stock sensors and then the wideband in there atm.

just need to know where to get power from for the wide band. as non o the ECU pin outs have a 12V ignition power listed at any of the pins.

I'm looking at the pin out but none of the pins read as a 12v ignition power source on it. Using the one in the FAQs

EDIT A25 and B1 both say PGM-FI main relay(power) would that be ok to use as a power source?
