The pink wire at ignition plug gets 9.36 volts with ignition on. When switch to run it gets 11.46. this is all with ECU hooked up. Without ECU hooked up I get 11.46 on pink wire ignition on and in run and same at pink wire at ECU plug. I was measuring the wrong wire other day when it was showing 4.90 at ECU so disregard that.
If this helps anything?

Zener's on backwards. Test measuring it both ways 1st before soldering on.
I've seen switches now where some has to face one way, and another has to face other way.
So only sure way to know for sure is to place it on contacts and hold it there.
Then measure output at pink wire at ECU connector.
Also keep battery on smart-charger 24/7. Voltage is too low to operate ECU properly when you're cranking. So even IF everything is perfectly OK, ECU's dead when cranking.
