I personally have 1988 GMC truck and had to replace the fuel pump. I found all the info including wiring diagram in a haynes repair manual. These can be purchased in most automotive parts stores. Something I found interesting is that the fuel pump's operation works through the oil pressure switch, located by the distributor screwed into the engine block. If this switch is stuck or sticking it will affect the fuel pump. Replaced a good fuel pump for nothing! The truck had sit up for awhile and the ground wire connections had to be cleaned as well.

Here is some information that I find useful when wiring trailer connectors, and the brake controller should be wired into the vehicles wiring according to the instructions that came with the brake controller and that identifies each wire from the brake controller.
Be sure that you solder all connections well for the best operation, and you should use 10 or 12 ga. wire for the Pos. (+) connection, and the ground or Neg. (-) connection, and you should run both wires all the way out to the battery, and about one foot from the battery on the Pos. (+) wire to the battery, make sure that you use a 20 or 30 amp Circuit Breaker and Do Not Use A Fuse.
The rest of these diagrams should help you to get your trailer properly wired up.
