Aftermarket Heated Seats

Does anyone know where to get seat heaters to install on a 2nd Gen?? I have seen them on some trucks next to the USB cluster. Is this aftermarket or a stock upgrade added by Toyota?

Welcome. Amazon and ebay are both places to start. Here's one of the many threads on the subject to get you started; https://www.tacomaworld.com/threads/anyone-tried-this-brand-of-seat-heater.358256/ . As you learn your way around here, you will learn that the search feature is your friend. Google is another, which will usually bring you back here anyway.

 

Thanks for the quick link... I was searching and nothing of relevance showed up. Figured there was plenty out there about this
