This are 91 F150 brakes parts that you all needed.
Try google and see some images for now, it might help you in getting in ideas
You might need to see if they are properly connected and clean terminals
Is it hard to compare the stock part to the new part you want to avail?
Any idea which part is repaired after the incident? check the steering linkages if they are in good condition? See the rubber boots, bushings. etc.
Something is in loose connection. Other cause by too much heat which melts the components. You need special tools to repair it
You need to open it manually by using a lever that can fit to the grill to press the lever. A screw driver will do.
Maybe your amp it getting too hot melting the other components and getting short
You need to change your seal to prevent the oil in getting inside the coil.
Maybe you can utilize something in your shop to fabricate your own tools. That would be the best for zero expense.
