i need help with what wire i got to tap into for my air and fuel i got the + and - now i just dont know what wire to connect the gauge to i found the 02 sensor and i see 4 wires which wire is it???
thanks
thanks
Please tell me you know you're not going to get any valuable info from tapping into a narrow band sensor like that. To answer your question though you'll tap into the two wires that arent the same color.
Does your gauge just have one positive input wire? What color wires are you seeing? Two of the wires should be the same color and you can ignore those.
its not that he wont get any valuable information, just not any good information
Tap the gray wire. Although Dyoel is right, you are just going to get lean/rich off a narrow band, you wont actually get an accurate reading of your air/fuel ratio. Only thing its really good for is telling you if you need a tune. You should just send it back and spend the extra coin on a wideband.
He means it's just gonna switch between lean and rich while cruising like a light show. At full throttle when you should really care it's still not gonna give you usable info.
Well what colors are you seeing? The last 4 wire I messed with had 2 grey wires for heating, a white positive and a black negative.
I'm talking about the wires on the sensor itself. Tapping into wires on the harness that can't be replaced easily is not something I can recommend.
No the greys should be heating only and won't have a signal.
Sounds like you're looking on the engine harness side and not the oxygen sensor side. It will probably be that regular white with a signal but I still wouldnt splice on that side of the connector since the other side can be replaced along with the sensor if needed.
ya thats the one im looking at 2 white ,gray and black???????????You tell me what sensor you're looking at. You should be looking at an upstream sensor either by the radiator or the firewall for a reading.
