I can see pands-xxx-pairing wifi but no idea what it gives me.
Panda has USB female plug same as my legacy USB plug. I doubt they want me to use the weird unique cable but Nick has the weird unique symmetrical cable and that gives me Unrecognized Device in windows.
Wow, this comma white panda is amazingly unclear for me.
I guess I need to simply find wiring diagram in FSM and see which head is wire 14.

if its a FWD application its the one closest to the fire wall

Also if you go into the FSM wiring diagrams Always POST the connector number.
Example E152 is the ECM connector

Also the ASCD (Automatic Speed control)(AKA cruise control) IS routed to the ECM and monitors for different voltages from the voltage divider....
Figured you might want to implement some sort of (Make a time stamp here in the logs when I press this button) feature for getting started.

As a general rule bank 1 always contains cylinder number 1.

Once I've enabled main relay output I got nice crank and both cam signals into rusEFI!
Two CAN milestones - I have gauge cluster displaying RPM and radiator fan is no longer wining in limping mode all the time looks like coolant temperature messages are being accepted by the vehicle.
Also got VVT position to synchronize once I've inverted cam sensor signal.

First time hooking up fully soldered Hellen on my daily driver!
ETB control works even while it should NOT have worked - ETB relay was supposed to be Lua-controlled and it just works without any Lua script? Weird.
It has been exactly two years since I've installed a HITACHI MAF0031 from Rockauto. Do I really need to get a new one? Weird.

Well, clearing those two harness grounds on passenger side fender has allowed me to pass inspection?! Either that or warmer weather allows ECU to test evap / o2 / something else much much quicker?!
On real car with MAF unhooked and poking into harness plug like on the picture, I do see 4.7v on pin 5 which is the pull-up of the intake air thermistor.
Does me not seeing similar voltage on pin 4 MAF signal mean that this MAF does not need a pull-up on the ECU side? Is there such a thing as a MAF sensor which takes automotive battery power in and produces nice voltage, not current output?
PIN 2 switched 12 volt power for your MAF
PIN 4 MAF signal wire
PIN 3 ground wire or low reference for your mass air flow sensor
PIN 5 switched 5 volt signal. (No it's not, it's intake air pull-up showing itself being a pull-up)
