Can the red power cord of the ignition advancer added by the oil-to-gas switch be connected to the power supply of the decompression solenoid valve?

I installed the igniter in advance, and the master of the maintenance station directly connected the three wires to+12V, which was grounded in black. I think it's a problem, too, but people say it's nothing. To put it bluntly, these maintenance masters are irresponsible!

Personally, I think the red line is connected to+12V behind the key door switch, the blue line is connected to+12V of the natural gas pump, the yellow line is connected to the signal line on the throttle, and the black line is grounded!
