I've purchased a Bosch premium O2 sensor kit with SmartLink. It comes with a wiring chart but I have 2 wires that are not on it. My original O2 sensor has a red and yellow wire along with gray and black. Which wires are the heater wires and which wires are the signal and ground?

    Can you bring the information to SE? as it is, this is a link only answer and is ripe for deletion. – Pᴀᴜʟsᴛᴇʀ2 Nov 1 '16 at 9:51
  • I think what @Pᴀᴜʟsᴛᴇʀ2 had in mind was a digest of what information the videos contained. – Lynn Crumbling Nov 1 '16 at 16:16
  • @LynnCrumbling - Exactly! Thanks for helping me clarify. No need for people to down vote this, IMHO. I'd just like to see the information posted here, is all. Hopefully The Heretic can accommodate. – Pᴀᴜʟsᴛᴇʀ2 Nov 1 '16 at 16:55
