LT headers and 02 sensor wiring
SW LT headers on a 96 A4 - does anyone make a wiring harness extension that allows me to reconnect my right side rear o2 sensor or do I have to fabricate something ? Thanks

I just left mine disconnected, but I have the rear O2s programmed out of the computer. I know what you mean about the wires not being long enough. Seems to make sence to just plug it in if it is there anyways. Or you could use an O2 sim there. What are you using on the drivers side?

Driver side actually has enough slack to fit.
On your car, how do you program them out, does it run correctly ?

A friend has the LT1 edit software and we bought another license to program mine like the tuners do. He basically told the computer to ignore all readings from the rear O2 sensors. It still reads the fronts. I haven't had any drivability issues or codes.

EXCELLENT !
Now if someone would help with the harness extension question, I'd be there....

LT headers and O2 sensors
My wife and I have a "96 Vette LT1 / 4L60E. I had my computer reprogrammed at PCMForLess to operate as an OBD1 system. This way you don't need the #2 O2 sensors. This was done while I was putting the LT headers on.
My cents,
