yes you are,, doing your best. and is harder on your end, for sure.
some DMM are blind to 200Hz signals, either too slow, has filter on the DC mode, or is reading peak signals on purpose (its not this last one)
but the ECU is for sure lost.
it is not regulating, per the video 2 test.
my guess 2 is the meter is not working...
you can test the idle switch key on or running.
the switch goes below 500 ohms and the volts on the pin go to near 0v. it idle.
this is the 1st step for idle controls. #1 most important. Usueally the ECU, will flash a code for bad idle switch but that takes driving with DIAG jumper in place to see this happen, and can be random fail on old cars. (switch is old,caused)
