1995 Ford Bronco/F-Series Engine Compartment Fuse Box & Trailer Relay Box Diagram
Fuse and relay chart mapping engine compartment fuse box positions (A-U) and relays including horn, fuel pump, PCM power, and trailer relay box.
This document is a layout diagram of a Ford engine compartment fuse box (power distribution box) and a separate trailer relay box. The main engine compartment fuse box diagram shows fuse/cartridge positions labeled with letters: A through K running up the left column and L through U in the middle column, plus one unlabeled slot at the top left. Along the right side of the box are five relay positions identified as the 4 WABS Relay #2, Trailer Marker Lamps Relay, Horn Relay, Fuel Pump Relay, and PCM Power Relay. Below it, the Trailer Relay Box diagram shows four positions: Trailer Battery Charge Relay, Trailer Backup Lamps Relay, 4 WABS Relay #1, and 4 WABS Diode. The diagram provides physical location and identification only; no amperage ratings, circuit descriptions, or fuse functions for the lettered positions are given on this page (a companion legend page may exist elsewhere in the album). A reader can use this page to locate specific relays (e.g., fuel pump or horn relay) and identify lettered fuse positions within the underhood power distribution box, as well as trailer-towing relays in the auxiliary relay box.
