I received a block heater as a gift.
The instruction that came with it are hopelessly useless, but the mfg's webpage indicates it is the right model my truck (2013 EB 4x4 crewcab).
I have seen suggestions that the plug it replaces is on the passenger side of the block toward the rear and that it is on the front of the block,
but I can't find anything that looks like the right place.
Can anyone definitively tell me where this goes? And what the plug I'm replacing looks like?
Thanks!
