Trying to find the correct relay
I have a 96 Ford F350 XLT gasser 460. The "power distribution box" in the
engine compartment is missing a relay that will allow the truck to charge the
battery on my trailer while driving. It's the 15amp relay in position 5 on the
diagram. I cannot find the part number to save my life. There is not one in there
right now so I can't get any numbers.
