I'm awaiting an importer to source me a NEO harness but figure no harm in asking, anyone have one for sale? haha would hella save me time.

I looked at pictures online and the NEO's. o2 sensor appears different is there somewhere stateside I could order from, I know FRSport could find one at a high cost. If anyone knows if my rb20 o2 can be wired up to work or any USDM replacement Id appreciate

so close to the end of this year long build I can't wait!

yes, it can. really any 3-wire o2 sensor will work, just resolder your connector on. 12v and ground for the heater (polarity doesn't even matter. it's a resistor), and the smaller shielded wire is the signal. i'm using a bosch from a 93 5.0 mustang, which was like $20 or $30.

Thank You! Makes me stress less about something else needing to be ordered last minute.
