Which two wires are the motorcycle kill switch wires?

Motorcycle kill switch wires typically run from the ignition unit to the key switch and kill switch, usually using black/white wires. Here are some precautions for riding a motorcycle: Pay attention to braking conditions: In case of an emergency, apply both front and rear wheel brakes simultaneously to prevent wheel lock-up caused by separate braking or excessive braking force, which could lead to the motorcycle tipping over or flipping forward due to inertia. Maintain steady speed: Always ride at a moderate speed, minimize the use of high speeds, and especially avoid prolonged high-speed riding. This helps prevent the engine from operating under heavy load at high temperatures, which can cause overheating or even damage. For long-distance motorcycle trips, it's advisable to stop periodically to let the engine cool down, preventing damage to the engine system from excessive heat.
I used to tinker with old carburetor motorcycles, and the kill wires are usually the black wire and the black wire with white stripe. The black wire is the ground wire, connecting it to the frame will stop the engine; the black wire with white stripe is the kill control wire, which connects to the ignition coil to cut off the ignition signal. Special attention must be paid during actual operation: always disconnect the negative terminal of the battery first to avoid short circuits! When modifying the wiring, it is recommended to buy special waterproof connectors, as exposed wire ends can oxidize and cause poor contact, leading to unexplained engine stalls while riding. The wiring harness is usually located below the handlebar switch or on the side of the seat. It's best to take photos to record the original wiring route during disassembly and installation.
