Whats needed to put rear O2's up front getting the typical long tubes error codes, what all do I need to put the rear O2's up front, any harness or anything like that, can they just plug up?
any links to places that would sell the harness if needed would be appericated.
I contacted LGm but have not heard back from them.
Thanks

I don't know about F-Bodies, but on Y-Bodies the plugs are different. In order to run the higher wattage rear O2 sensors up front you need adapter cables. I know LG Motorsports sells them.

Wait wait wait.... what car are we talking about here. On an f-body, front and rear are interchangeable. No difference in sensor at all, only in the wire pigtail length. Now on the vette, the rear sensor has a higher wattage heater than the front, as well as a 2 foot+ pigtail. The vette rear sensors will work without modification in an f-body as they share the same square 4 pin connector. However to use the rear vette sensors in the front of a vette with LT headers, you need an adapter, since the front vette 02 sensors have flat 4 pin connectors.

Personally, I think its a big myth that splicing lines will raise the resistance perceptibly. I think theres far more danger in simple hit or miss manufacturing of the o2 sensors itself. I recently bought a brand new one that crapped out in a week and a half, exchanges that one for another identical sensor and have been driving fine the rest of the winter. Even if splicing it did raise the resistance, an adaptor would do the same.
