The wideband has 2 outputs. Usually a 0-5v and a 0-1v. You'll have to read the manual to figure out which is which. The 0-1v is the one that you connect to the ECU. Simply run a wire over to the ECU from the wideband. Find the O2 sensor wire in the wiring loom coming out of the ECU, cut it 6-8" away from the plug, and connect the wire from the wideband to the wire going TO THE ECU. Leave the wire in the loom disconnected. If you're feeling froggy, you can remove the stock O2 sensor, and buy an O2 sensor plug, but there's no harm in leaving it in there to plug the hole either.
