Engine Block Heater Location for a 2021 Toyota Tundra

Question

Question:

2021 Toyota Tundra 4wd, I have tried to find the cavity on my engine to get this block heater installed but for the life of me I cannot find it. I read the extremely vague instruction sheet that came with it but still cant find it. Is there any way you can help me locate the proper install location? Thanks, Chris Cavalier

Christopher, I did some research, and it looks like it should be by the exhaust on the driver's side of the engine, underneath the driver's side door. Immediately behind the driver side exhaust header there is a factory designed hole for the Kat's Heaters # KH11813 block heater, with an electrical connection mounted beneath.

Thanks Bryce! Found it, installed it. Super easy, the only complaint might be the lack of heat protection on the wire but other than that it went great, thanks again!
