2007 Mazda MX-5 MURANO P0037 Code - O2 Sensor Heater Circuit Fault After Tune-Up

After completing a recent tune-up on my 2007 Mazda MURANO, I'm now receiving a P0037 check engine light, which indicates an issue with the oxygen (O2) sensor heater circuit. The only potential cause I can think of is that during the adjustment of the plenum bracket, I may have stretched or damaged the wiring connected to the back of the plenum on the passenger side. I'm wondering if this large connector located at the rear of the plenum is part of the O2 sensor heater circuit system. Any confirmation or advice on whether this component is involved would be greatly appreciated.
