Block Heater diagram
 

Does anyone have a diagram or photos of the wire routing for the NAH block heater?

My car came with one, but the wire is coiled under the hood, not routed down to the lower grille as it should be. Unfortunately the routing from the upper radiator fixing point downward is not obvious, and I'd rather not book the car in for an appointment if I can easily do it myself.

Thanks!
