Jumping switches

I'm planning a 3 switch panel using the narrow Toyota push button switches in the cubby of my 16 ORLB. These switches come with a connector and associated jumper wires. I'd like to jump these switches together out to a fuse/relay aux box under the hood. I'm thinking all neutrals can be jumped out to a buss bar, power wire seems logical, but jumping the switches to relays I'm confused about. How do I do this? Or would it just be easier to keep 3 separate circuit wire bundled together? That seems like a big wad of wasted wire.

Hope this makes sense............
