What is the wiring diagram for the 6 wire 02 sensor that is included? I want to hook up to a 4 wire bosch 02 sensor instead.

It has instructions for how to wire the gauge into the wires from the O2 plug. But the plugs are standardized, so you shouldn’t need to rewire it. Just plug it in.

Is this kit more reliable than the AEM ones?

I wouldn't say it's more reliable but it's saying it's close I've been using mine for about a year with no issues

Anybody got a color scheme for the wires? I've lost the instructions.

its just red key on hot black ground the other two are for another gauded of like for your cars ecu those are white and blue you don't need them jusy red and black for stand alone also you can look in the AEM website it's a copy of that
