What's up guys, I'm new here and have a question about an Ibanez switch I'm getting for a blackout install in a newer RG7420. I am replacing the cor-tek original 5 way blade with a cor-tek 3 way and I noticed in some photos and wiring diagrams there are some metal jumpers connecting 2nd-3rd and 4th-5th and 6th-7th on the tabs on the switch and in some (such as the stock photo) there are no metal jumpers. Am I going to have to put some metal wire jumpers on there if there are not any? And what do they do? If it is already a 3 way, why would jumpers need to be installed yourself to make it work? Thanks to anyone with input in advance, I am enclosing a diagram of what I am doing and the switch in the diagram has the jumpers like I am talking about.
