After I had my exhaust put on my car, I noticed that the check engine light was on. The code was the O2 sensor. I looked for the connection under the hood and found that the end running from the exhaust was one bare wire that had been stuffed into the end that runs out of the harness. So i have one of the stock ends and an end that just bare wire meshed together to try and form a connection. Obviously this isnt working. What's the best way to fix this?

 

Replace the connectors with something else. Preferably WeatherPack style, but almost anything will do as long as they are properly insulated (heat shrink tubing).

Remember that the O2 wire to the ECU is shielded so make sure to make your connection to the inner wire and not the shield.

 

Ok so i'm just going to need to find some new connectors. I'll see if any local hardware stores have any, thanks!
BTW, I love your avatar, Fight Club was the ****!

 

Can you not just wire the two together directly and wrap them with electrical tape?

 

You can find common male/female spade connector to crimp on the wires at ANY auto store plus WALLMART. Or you could just butt splice them together. Or you could solder them together and install shrink tubing over the joint. You MAY NOT twist them together and put electrical tape over the mess. Tacky

 

^Thanks

 

bad idea... it'd be like trying to secure a front bumper with hair.

 

Because that's wrong. So very, very wrong. While it will work, in about 6 months it will become intermittant...Spade connectors covered with heat shrink is about as simple as you want to go. If you have access to WeatherPack style connectors then they are a much better choice but not as cheap nor as easy to work with.
