I'm using this kit to toggle my ABS on the fly on my Yamaha MT07. This is so I can practice stunt rides in the parking lot. Much quicker than taking the seat off and pulling the fuse

Pure tinned copper, excellent quality wiring harness. I'm only pulling ~20A through it but it's been rock solid. Not just for fuel pumps - use it for any accessory you want.
