2004 dura max question

[LloydMcCoy]

I can't find the friggin plug for the block heater. Anyone have the truck that can tell me where it is.

[Swampa]

Not sure on the 04 but the later models are under the passenger battery next to the fuel filter. Black cord usually clipped to itself.

My '05 has it by the coolant jug on the passenger side above the frame.

Look under the passenger front fender well. Pull back plastic alittle and it should be in that area. Maybe?

[BETTERLUCKYTHANGOOD]

Hadn't ever looked for mine, guess I should.

It is going to be a coiled up wire and the plug has a cover over it, so if you are looking for the "plug" you won't see it.

I have an 02 and its under the passenger battery box or wedge between the coolant tank and battery

Found it.
It was folded and zip tied to positive lead down low passenger side

[BrianL]

That looks like it. Fish it thru the front grill just above the bumper and leave it there. Nice to get in and have instant heat. I plug mine in even parked in the shop.

Don't forget your winter front cover and anti gel
