The power windows in my 1986 D150 stopped working after I installed a stereo and I am searching for anything that I may have disconnected or disturbed, I'm trying to locate the power window lift relay. There are a few electrical components that look like relays to me between the steering column and the ash tray but the wire colors and configurations don't match the schematic and they are square/rectangular shaped. (The closest replacements I can find are round can shaped.) If anyone has a good source for electrcal components for this era vehicle that would be helpful also, this truck loves electrical bugs

 

ALLDATA and PRODEMAND are IDENTIFIX are all good sources....
But I think that relay is out under the hood in the Power Distribution Box?
Keep us posted... Good Luck...
