So weve been reaching into the single digits at night, and i figired id ask. How long does the block heater need to be plugged in for to be effective around 0 to -10? I start my truck at 440 every morning and give it about 5 minutes of high idle time usually. With the block not plugged in.

I only ran my 08 1 year of winter. I had it on a timer set for 2 hours and it always performed excellent...to the point that the glow plugs hardly cycled. That was garaged at night in 20 to -20 degree night time weather.
Last year, at home, 45 minutes to an hour. Whenever I got up for work in the afternoon. Got up, went outside, plugged it in then preceded to get a shower and whatever for work.
While I work, it's plugged in for the whole 12 hour shift... cause I am not venturing back out in the cold, and I'm not paying for it

On your LLY, it's farther forward. Look to the WIF harness coming from your fuel filter. Just forward of where you unplug that and below the air intake, look for it bundled up with a zip to the existing harness in that area.
Don't try and pinch the zip with cutters, just use the tip of a utility knife inserted, with the edge pointing back toward you, so you don't damage the cord.

Have mine on a timer for 4 hours before I leave for work, or it is on for about 2.5 if I have to plow.

These heaters are pretty powerful and warm things up quickly. An hour is fine. Anything longer than 2-3 hours is a waste.
The "Law of diminishing returns" comes into play here. The greater the temp difference between the heater and the atmosphere, the faster it loses heat. So you'll see a rapid rise in temperature when it's plugged in, and this rate slows as it approaches steady-state.
Those with timers and steady ambient temperatures can check their ects in the morning and see how less heat time doesn't reduce ect much.

Solid, i appreciate the answers. I kinda figured an hour would do, i just dont want to add another 100+ dollars to my electric bill if i dont have to.
I would simply plug in before went to bed, then unplug before went to work. Of course, live in Texas and only used twice the entire 4.5 yrs I had my LMM.
My new LML lives in the garage now, much warmer inside when cold and will most likely never need to use the block heater.

Plugged mine in last night for the first time (low 20s). Interested in seeing what the difference is going to be in vehicle warm up this morning. I throw a jacket on and a hat, sometimes Carharts if windy, and I'm usually good. I overheat easily. Rarely been using the seat heaters unless my back is hurting (love that I can turn on the lumbar heater only for this). The truck on the other hand... I want to make sure it has plenty warm up time. I know what it's like when we get older, and have a few miles on us, for the need to warm up quite a bit before over exerting ourselves
