Do you already have a wideband lower down in the downpipe? if your wb controller has a 0-5V output, you could just wire that up to the haltech, and you should be able to do closed loop with it. then you wouldnt need the other o2 sensor

The other option would be to just replace your 4-wire with a stock narrowband o2 (single-wire) and wire it to the haltech o2 sensor input
