I bought the recommended bosch lsu4.2 o2 sensor, but the wiring diagram only shows 4 wires. Mine has 5 wires? How do I wire this up to the s300?

You cannot just wire a widebnad sensor to the ecu. You must use a wideband kit. We recommend the PLX Devices kits. http://www.hondata.com/techplxwiring.html

I guess I am not sure what kit you are referring too? Are you talking about the sm-afr? So if I understand right, the O2 sensor hooks up to the sm-afr and the sm-afr hooks up to the hondata ecu?
