red and yellow wire soldered together

Question

Hello and thank you for your potential help. I have a radio that only works if the red and yellow wires are together. Even when reversing the colors, it does not light up. Is there a risk? Thank you

Configuration: Windows / Edge 89.0.774.57

Thank you for your response. I noticed that the red wire on the ISO doesn't correspond to anything in the car; should I unsolder it from the yellow? And connect it directly to the battery? Thank you.

do not confuse the red wire with the fuse with the red arrow designating the connector

No, I'm talking about the after contact; I soldered it to the yellow 12V permanent, otherwise it won't turn on.

Redbart · Answer

easy solution, but incorrect, because this setup will draw current from the vehicle's battery while stopped

must be connected to a line cut when the ignition is turned off, see fuse box
