Electrical Schematics for 93 F150

Does anyone have a source for the electrical system schematics for our trucks. I am finding more and more PO alterations and I cannot explain why he did them. I even have speaker wire being used as power and return wires for the power lock system. I need to see what the hell this assssclown was thinking.

There are a few schematic wizards around here who will hopefully come up with something from you.

Previous-owner wiring changes are definitely terrible. I find often undoing what they did, and putting it back to the way it should have been almost always fixes problems.

Thank you very much. Does anyone have the same for the power mirrors. I got the switch and it does have power but the mirror still do not work. I want to verify the wiring before I buy mirrors. Is there a check for the mirrors to find if its the new used switch I got or if its the mirrors. I did check the door locks and the actuators are grounded. I know what I have to do there anyways.
