This document is a labeled layout diagram of a Jeep Power Distribution Center (PDC), the underhood fuse and relay box. The diagram is divided into lettered rows. Row D holds the Engine Starter Motor Relay (pin cavities 13, 14, 12, 10, 11) and the Fuel Pump Relay (pins 6, 8, 5, 2, 4). Row C holds the Cooling Fan Relay and Automatic Shut Down Relay with the same pin patterns. Row B contains the Fog Lamp Relay No. 1, A/C Compressor Clutch Relay, Fog Lamp Relay No. 2 (DRL), and the Controller Anti-Lock Brake Relay, each with numbered pin cavities. Row A shows a bank of cartridge fuses labeled F16 through F26 with amperage ratings ranging from 10A to 25A and their cavity numbers (1–24). Below is a block of larger blade fuses numbered 2 through 15 with ratings including 20A, 30A, 40A, and 50A, each shown with its cavity positions (1–28). At the bottom, main power terminals M2 (Generator) and M1 (Battery) are identified. A reader can use this to locate specific relays and fuses in the PDC and identify fuse amperages by position.
