As you know the 84222-12010 fails pretty often on our trucks. Its located on the transfer case, as well as the lockers, and causes the indicator on the dash to blink even when they're working. I recently had the one on the rear locker fail on mine and wanted a cheaper alternative than 60 bucks, so her you go. NAPA Pt# NS6421. Its a neutral safety/reverse light switch found on many toyotas and is exactly the same as the 84222-12010. Retail price is 22.49
