4.9 LSU wideband sensor wiring

Post by turbofreak » Sat Apr 29, 2017 9:57 pm

I want to make sure I don't burn up the sensor or ECU.
Laminated card for 4.9 sensor shows
WBO Ip
WBO VGND
WBO Heater
WBO Heater +
WBO Rcal
WBO Vs
All pins labeled the same except I don't see a pin for WBO VGND. WBO Vs/Ip is the only open pin left. Does VGND go to Vs/Ip?

Took a gamble. Attached to that pin. All good.
