Hi guys I have a 87 ford f350 with the 6.9 NON TURBO diesel. I have been hauling a 6k pound pintle hook equipment trailer with 12k pounds of weight on it. The truck pulls it good considering it doesnt have turbo but I ordered a resistor mod for the truck and its telling me to wire it in with the IAT sensor or the maf sensor. I'm not going to act like I know what I'm doing because I dont. I live in the country not near a garage worth driving to. The instructions says it is idiot proof but apparently im an idiot. I called the guy that i ordered it from and he said liik on the air cleaner somewhere for the sensor but my truck doesnt have any on it. How do I hook this up? does someone have a picture or diagram of my motor that would show where it goes. Thanks guys I know probally one of the more retarded questions asked but i've been looking for it all night and im stumped.. THANKS!
