How do I connect a Wideband O2 Controller to my ECU?

The Log Box Pro, Log Box v2 and Log Box v3 all have a reverse RJ12 (telephone-style) connector which allows a direct digital connection to the Zeitronix Wideband O2 Controllers. When you purchase a full Log Box or Log Box Pro package for your bike you will receive an RJ12 cable in the Installation Kit. You just plug the RJ12 cable into both the Log Box and Zeitronix Wideband O2 Controller (ZT-3). 

Note that the RJ12 cable that we use to connect to the Wideband O2 Controllers is not an actual phone cable as it has a special pin out (crossover cable).  The connectors on the ends of the cable are shown here for reference:

The Log Box v1 requires the 0-5v signal from the Wideband O2 controller to be wired into a pin on the ECU. The wideband is connected to the pin on the ECU that the stock narrowband O2 sensor connects to. You can simply cut the stock wire close to the ECU plug and solder the Wideband O2 analog 0-5v wire to the wire coming from the ECU. Or alternatively you can utilize the stock O2 sensor harness.
