Default Rats ate my wires

Just looking for a picture of the wires from the A/C compressor, one white wire in particular, need to figure out where it is attached and a red and black wire that comes out of the fire wall. I have attached a picture

It would be helpful if you can tell us exactly what year truck this is, and which engine. The wiring diagrams vary by engine and by year. I've got a 1996 5.0, and the compressor is on the other side of the engine. So... knowing the year and engine are important in order for us to help.
