well, its in, after some cussing and knuckle busting to tighten the hose clamps. Here's what I did.

I mounted the coolant heater using the supplied strap near the lower right (passenger) corner of the rad (after drilling a new hole between the existing 2 in the strap) . There is a small hole in the subframe there that was able to use. I chose this location because the heater was out of the way of all the accessories, and it was as low as it could go. In fact, it is lower than the oil pan, which is important because this style of heater relies on convective circulation to flow coolant. I T'd into the heater line up near the oil filter - ran that hose across the back of the block and followed the heater line down the passenger fender to the OUT side of the coolant heater. I then T'd into the heater hose that i followed down - the one that comes out of the water pump and took that line to the IN side of the coolant heater.

I'd rate this a 2 banana job (out of 5) due to having to twist my hands like a contortionist. All total, took about 2 hours - probably would have gone faster if it wasn't 26 degrees out.

I opted not to do the in hose type like diesel giant has because I could not see how it would circulate through the block that well. I am not saying they don't work, I just think the circ type work better (based on personal observation of friends diesel and gas trucks/cars). Also, I realize that will lose heat in the 4 foot hose run that the coolant makes, but I think the 1500w will make up for that, also, once the flow starts, it will move fairly quickly through there. I will try to get a picture up if i get some time this afternoon.

No prob on the confusion nick. We are all a liitle S l o w in the am.

Oh and it would seem that my routing reverses the flow when compared to the schematic, but I think it should be ok since it goes from low to high like it should
