If some one has a wiring diagram for a VL can you tell me what the wiring is for the 02 sensor attached to the exhaust manifold? It’s a heated sensor and has three wires black (neg?) red (pos?) and white (sensor?)

I just want to be sure before I hook it up, so I don’t cook the tester

Background
I’ve made the cheaper version of those O2 sensor kits from jaycar. I know its narrow band but because it’s not closed loop injection, but a carby it won’t flick from rich to lean and back constantly. If I can get the cheap one to give me some reasonable data I’ll go for the more expensive kit. This one doesn’t just have LED for rich, OK and lean it gives you a digital readout.

The advantage of this is you can run it in the car as you drive and effectively do a real world dyno
