Greetings all--newbie here. I just bought my first F350. It is a 1995 4wd dump with factory-installed plow package. I have spent the past week removing all the plow controls and sander wiring. I discovered too late that the plow controls and wiring were factory installed. To remove the plow light switch I just pulled the wires off the back of the switch, and pulled the wire harness through the firewall, only to find it is all beautifully bound into the headlight harness. I did not discover until afterward that the switch is labelled Plow Lights / Headlights, not Plow Lights / Off. Accordingly, I made no effort to match the wire colors to the correct terminals. The switch is a very simple up / down toggle with six blade terminals on the back. The only way to distinguish which way is up is that on the back in the middle among the blades are the numbers 11 and 0. Is it reasonable to assume that all such trucks were wired the same ? If so, where might I find a wiring diagram ? Thanks in advance.
