Expand secondary air pump and solder resistance?

Well the stupid part is broken with me and now I finally want to eliminate the error. But I will certainly not spend 500-600 euros for the nonsense. I will simply expand the part and wanted to ask if it would be enough instead of the pump to switch the fuse between? If so how big should this be? I have something of 2-3ohm??? Does someone ever have a photo on which man recognizes where the pump is sitting!? I don’t have to expand the part, just pull the plug off and the Wi or can I also install the resistor in the engine compartment in the fuse box? Greetings
