Hi to everyone, dan here. been trying to find a diagram for my 06 HO 5.9....Its a single heater relay and its missing. It was taken off by the previous owners. Id like to get rid of the code that was thrown by it being gone and hook up the relay I just purchased. Pretty simple so far....two prongs small and two prongs large. I know it goes under pass battery and there are wires hanging there to receive it. I also have a huge black cable (ground coming from the grid. I believe this goes to neg term on the pass as well....anyone done this before... All the other threads explain this process for the two relay systems? I dont want to fry anything by hooking up incorrectly, any help would be greatly appreciated....thanks again....dan

 

did you get it figured out i have an 06 in the driveway i could go look

 

i did....thank you. I have not hooked up the two main cables yet tho cause I fear Im going to fry somthing? wanted to wait until our snow days went away first. however, with the two small ecu wires hooked up, it seems to talk with the ecu anyway and the check light goes off after threee cycles and then back on again after three days.....maybe just the super cold days i dont know?
