Default What pins for LC-2 Wideband?

Hey, so I am on the finishing touches to my 96 Civic boosted track car. I am not 100% sure of how to hook up my LC2 wideband. Here is how I am thinking I will be wiring it in. Can anyone verify that this is correct? I don't want to damage anything. Since I am OBD2a, I went off obd2 pinout so when I convert to obd1 with the jumper harness to use Hondata, they should be right. I have seen several different ways to wire it, but I am not sure which way is the correct way. Help is appreciated. Thanks!

Red wire: A24 (power source)
Black wire: Frame ground
Brown wire (analog 2): D16 (ELD)
Yellow wire (analog 1): D7 (primary heated o2)

This is pretty much how I did mine, dont use analog 1/2 for wideband, use those for something else.

yes that works. but only AFTER you install the hondata ecu. if you try running the obd2 ecu with it wired like that you'll have all sorts of issues.
and you'd be better off wiring it into the conversion harness instead of the factory harness, for the sake of anything in the future you should always try not to modify stock wiring whenever possible.
