Hey guys, I’m having trouble wiring a Bosch O2 sensor. The colors on the connector are Purple, Pink, Black, and Tan. The wires coming from the front are Gray, Gray, Black and Red. Any help would be appreciated!

Best advice

Return the wire in sensor and buy one that just plugs in. They aren't much more expensive and the headache of wiring them in isn't worth it.

Bosch sucks a lot of the time on a LOT of our cars....only use Denso sensors.

Agreed. They're cheap because they are junk. But even good ones like Denso, NTK, and Delco are cheap, I believe like $25

Words of wisdom.

Have done 02's several times and I have always skipped the hassle of a wire in sensor.

OP, I will add this:

A tiny bit of anti-seize on the threads of the 02 sensor also make it easier to get out next time. I like Denso 02's comes with anti-seize.,has tapered 1st thread and is easy to thread correctly on the first try for the casual enthusiasts like me.

Bosch is decent but I've never had one of their 02's last 50,000 miles, typically failing after 45,000 miles on both stock and mod'd cars.
