I don't know that the swap will work as I showed, but the ignitor is after the coil negative, with no positive feed, according to the 1983 wiring diagram. So, not sure if you're mis-remembering the above. I just compared diagrams, the 1983 diag. is Post #14 above.
You posted a component diagram, not an electrical diagram.
The stock 280ZXT Ignitor (Power Transistor, Electronic Ignition Module) is grounded to the frame and has two wiring connectors via a "T" shaped connector on the ignitor: B/W from the ignition switch = battery voltage at IGN ON and Y/W = signal from ECU to fire the coil. The stock Ignitor passes power to the coil "+" terminal via a short B/W from the Ignitor to the coil. The output from the Ignitor is an L (blue wire) that runs to the coil "-" terminal. The
amplified output of the Ignitor causes the coil to spark. I would say: look at the Turbo electrical diagram and you'll see what I'm referring to.
I don't think I'm "mis-remembering" anything (apparently, I WAS!) - I've been over this dozens of times with multiple people and hands on with the stock coil/ignitor on numerous occasions. I don't know if the PRW-2 will work as intended, but I used one (unknowingly) with my F31 (Infiniti M30) engine management system for years. That was with the stock F31 coil and wiring harness setup however. I've never personally used one to drive the stock 280ZXT coil. However, it'll be an interesting replacement if it works for Ricky...
But, the scheme follows the diagram above where the transistor "base" is connected to the Y/W from the ECU,
the transistor "collector" is connected to the B/W (battery voltage @ IGN ON) (transistor "collector" should be tied to GND) and the transistor "emitter" is the L output to coil "-" It could be that the PRW-2 will perform the same function.
I would say yes. Sorry for my mis-information, the transistor "collector" should be grounded (not powered) so change the power wire to GND.
I'm interested to know if this works as a replacement, so be sure and let us know. And I hope you've double checked and cleaned your wiring connectors...
