whats up guys fumb question but im have issues wiring up my guage black ground red power and purple i have connected to the White wire directly on the O2 sensor. the problem imm haveing is as soon as i connect the puplr to o2 iu lose all guage power, but if i disconet just the pule it lights up again? anyone haveing this issue? thanks

 

Honestly, I'm going to be blunt, Those gauges aren't worth shyte! Sell it for as much as you can. The stock narrow band O2 only has a 0-1v signal.

However if you want to wire it up you would be better off wiring it directly to the PHO2S pin @ the ECU. What model and year car are you hooking this up too?

 

white from the o2 isn't the signal wire( assuming its a four wire; Black, grey, two whites) . what colors are your o2 wires. And why didn't you do research on o2's. If you're using the gauge for anything important you should have bought a wideband instead.

 

Depends on the chassis, however most Honda O2 sensors I have worked on have
2 black (or BLK/YEL & BLK/WHT)
1 white (or WHT/RED) and
1 green (or GRN/BLK)

And the white (WHT/RED) is usually the O2 output signal. However, it is still better to get the signal from closer to the ECU.

 

i looked up on it and it said use the white and i belive mine is the came as this 4wire

 

and its going on a 94 Cx eg hatch

 

i also have vafc on the car

 

OK so if you are looking to do any sort of AFR monitoring. Drop the narrow band O2, autometer gauge and get yourself a real wideband O2 sensor and gauge.
