You wouldn't wire it differently between the 2 programs, but you would do it diffrerently if the ECU is not yet chipped.

If its chipped, wire the wideband signal into the ECU. If its not (i.e., its still stock) wire the narrowband signal into the ECU. The wideband signal will confuse a stock unchipped ECU.

Also, make sure that you cut the signal wire off from the stock o2 and run the PLX wire to the ECU INSTEAD of the stock o2 wire.
