Tpi O2 sensor using headers I have a BOSCH 4 wire universal O2 sensor and i need help with the wiring, Black goes to the purple signal Grey is the ground White #1 goes to a 12v switched White #2 Is where i need help, i read somewhere it goes to constant 12v source? would that drain the battery? please help |
Re: Tpi O2 sensor using headers checking back,,,,,,nothing guess i'll goggle research |
Re: Tpi O2 sensor using headers its easy, the whites are the heater circuit. you ground one and +12v ign. sw the other and like you said, grey goes to ground and black is signal. i like to use a relay for power on heated o2 conversions |
