My block heater was installed by the dealer before I took delivery. I think it's the same as yours. The two-wire cord comes down from the heater (reddish-brown colored connector at the heater) and then makes a sharp 90 degree bend. At that point it's quite close to the heat shield, but then runs forward and somewhat up, so for the most part it's a reasonable distance from the metal. As Viceland noted, the cord, from the heater out about six inches, is covered by a black, braided, heat shielding tube. The braided tube, where the wire bends 90 degrees, is in loose contact with the exhaust shield, but the wire inside is not. The wire then runs forward to the lower radiator hose where it it tied with a black plastic "zip" tie. The original installation had the cord then go between the radiator and it's support, and exit out the front bumper, where it would be readily accessible but, in my opinion, also subject to the harsh environment of our salty and wet roads. Instead, I pulled it back behind the radiator, and up to the windshield washer reservoir, where the cord is draped over the top between the yellow cap and the metal cross member. (I use the heater only occasionally, so I'm not averse to having to pop the hood to retrieve the cord at those times.)
I tried to get underneath to take pics of the heater area itself but found I'd have to remove the right side splash shield to be able to see the block heater clearly. However, if you need more details, I can give it another try.
I managed to get the camera into a position underneath to show the routing.
Photo #006 shows where cord is connected to the block heater and makes the 90 degree turn. The braided heat shield is also apparent. It then twists up, and is tied to the oil dipstick tube, also visible in this photo. Tieing to the tube keeps it alway from the exhaust.
In photo 002, it then comes from the left side, over the exhaust, and jumps to the lower radiator hose where it is also zip tied (upper right).
In photo 007 it makes another jump over to the area adjacent to the windshield washer tube, and then goes up. This is shown more clearly in 008, where it is tied to the ATF lines and to the upper washer fluid tube. (Originally it went forward from the tie to the ATF lines, and out between the radiator and the frame to the front. My change was to route it straight up to the washer fluid fill tube.)
009 shows the cord in its storage position, draped over the the top of the washer fill tube. In the photo, the cord comes up the lower side of the tube, drapes over the top, and the plug hangs down on the "upper" side in the photo.
