E36 Expansion Harness Help

[chrisconboy1]

I posted before about wiring an electric fan up with the G4x into my e36. But I was looking into the expansion harness ( XS Expansion Loom (XSL) ) I also need to wire in the wide band o2 sens. Is it possible with this expansion harness to wire both into the extension and if so how would I go about doing this?

Thanks!

More likely you'd want to use the OE oxygen sensor plug. The expansion harness has a sensor ground and analog input you could use, but no power or chassis ground. Typically a wideband needs all 4. 

If you use the OE plug, it has B+ on the green wire, chassis ground on the brown, black is sensor ground, and yellow is pinned to AN Volt 3. When I did an E36, I cut the plug off and wired it to a DT plug.
