Does anyone know where I can get the 3 wire O2 sensor so I can run some leaded race gas? I have a dp, mp, straight exhaust and Power FC, does anyone know where I can get the O2 sensor for this to work? Thanks.

PS, I think it's a Ford...

Can someone please tell me how to hook up the 3 wire O2 sensor so I can run race gas? Thanks

Hook the extra wire up to constant 12volts - its what heats the thing.

 

My stock O2 had 1 wire... now I have 3... So I take it the black wire is the 12V and the other two white ones???? Thanks for the reply.

Sorry - I did have my head up my *** when I replied. The black wire goes to the same place the original went - the white wires go to 12v and ground for the heating element. Basically if you leave the white wires unconnected, it acts as a standard O2 sensor.

You might also be able to rob the plug that fits directly from an engine harness in a junkyard or get it at a Ford dealer just to make things neater.

 

Thank you for your help. I guess it doesn't matter which white is hot and which is ground (at least I hope not) cause I'm about to hook it up. Thanks again
