Standard Ignition Ignition Switch P/N:US-657
Bring reliable key-turn control back to your Toyota with the Standard Ignition Ignition Switch US-181 (also written US181). This ignition starter switch drops in as a direct-fit replacement for the 1989-1995 Toyota Pickup and the 1990-1995 Toyota 4Runner — see the Buyer's Guide tab for engine-level fitment. It routes battery power through the accessory, run, and start positions as you turn the key, energizing the starter and the vehicle's ignition and accessory circuits.
Signs the original ignition switch may need replacing include intermittent power to accessories, a no-crank condition when the key is turned to start, or the engine cutting out while driving. If a failed ignition switch is the cause of these symptoms, this unit replaces it; diagnose the circuit before ordering to confirm the switch is at fault.
