I wasn't thinking about the relay, the "black box" I was referring to was the control unit/module. Do you have diagrams of the internal workings of the control module? If not, my wiring diagram should suffice. I have a pretty decent wiring diagram from friends "mitchell on Demand" system.

It makes sense that the control unit/module probably would use a transistor (or maybe darlington pair) to gate on and off with a varying pulse width determined by the associated O2 sensor circuitry. Whether the frequency valve is on the collector or emitter side I suppose doesn't affect our musings here...

Time to call it a day before my posts start to make less sense than they normally do! ;-)
