Question type: Maintenance & Repair

I bought a 1977 f-150 custom.  Don't have an owners manual.  I know this is a dumb
question and should know, but I don't.  None of the repair manuals mention Warning
lights.  After laughing any help will be appreciated.

Not completely sure about yours but on most you can Remove your instrument cluster. When doing so you will see small light bulbs inserted in the circuit board. Most all of these will be back lighting. But with close inspection of the circuit board you can follow the circuits connecting all theses dash lights together. Any of the bulbs that appear to be on another circuit of the circuit board will be warning lights.

I have the number. But I was trying to order from Bronco Graveyard or LMC trucks. Their numbers don't match. I will go to the dealer and get them to tell me which board to order.
