I just want the schematic for the fuse locations.
yes
that depends on what engine both trucks came with.
No because they are 2 compleatly diffrent body styles
1985-1988 ford f150 f250 and f350 or a 1994 f150 f250 and f350
The plug should be hidden in the bumper in the vents.
Driver side of the engine low back.
start by taking the tires off
yes it should
It's on page 171 of the owners guide, or in any Chilton, Haynes, Clymer repair manual which covers a '86 f350.
Mine does not have a block heater. It has a oil heating element on the top of the oil filter housing. It's a '99 F350 7.3l diesel.
Best guess- bad connection in the block that connects the lights.
