help with electrical shortcut (1 Viewer)

My truck had a problem inside the fuse box. I was in the countryside and was able to drive it home without towing it.

now it turns on but the engine shuts off. probably the diesel pump is not getting current.

does anyone have the wiring diagram for ln106? does anyone know which one is that burned red wire in the bottom left corner of the picture, according to the wiring diagram?

LN65 owner here and I used this EWD as it is a generic diagram for all Pickups MY85-88?

Im not familiar with LN106 but if it same as my 2L system the fuel cut solenoid shouldn't cause intermittent running issue, either the engine runs with 12v at fuel pump solenoid or 0V immideatly stops. If the engine is running briefly you probably have 12v there or it wouldnt even fire up.

I can look at my factory service manual when I get home tonight. I also have an LN106. I will get back to you.
