No 12v to bank 2 downstream O2

After installing my Whipple I've lost heater power to this sensor. Pretty obvious I did something. The thought of troubleshooting this gives me a headache. I'll have the truck jacked up with the exhaust manifolds off today and will look for the obvious like a damaged connector or a wire pulled loose. Other than that any suggestions on what to look for?

I visually inspect the harness for the 02 sensor and see if it got smashed during the install. That would be my guess, it’s pinched somewhere. Find the damage and repair it.
