Cabin Fuse Panel

This information is no longer relevant, left as-is with no updates planned as of 10/09/2025.

REASON: This information is no longer maintained, and has proven to be of little feasible use.

This is a more technical page, if you are simply looking for vehicle-specific fuse and relay information or minimum required fuses, see HERE instead, and for general relay information, see HERE

This page is a half complete mess from an idea that went as well as a lead balloon. The only reason this page still exists is due to the time it took to create, and the hope that someone can make sense of anything discovered in here. Every attempt has been made to make the notes here legible, but this is not guaranteed.

the cabin fuse box has 9 individual electrical plugs (11 sections) that comprise it’s wiring, and as such the wiring has been divided as below per section.

All diagrams assume that you are facing either the front or the back of the cabin fuse panel, with the relays at the top.

Pictures of how the fuse panel should be facing you from the front a rear respectively

Reading this guide

Use the legends table below to decipher what each code means. This was made in order to make more sense of the pins on both the front AND back of the cabin fuse box

Fuse & Relay Connectors (Front)

These connectors are identifiable according to the annotated image:

The P/WIN and AMP fuses are not marked on purpose, both because they are clearly marked AND because depending on the manual, these have different designations, which overlap with the existing fuses in the bottom

Main Fuse Cluster

Below is a layout of all fuse block pins:

relay 1 - A/C Relay

This relay is a the only full-sized 5 way relay connector present in the cabin fuse panel. For the following assume the following layout:

Pin definitions

More information: Relays

relay 2 - TAIL Relay

This relay is a half-size 4 way relay connector. For the following assume the following layout:

Pin definitions

These half-size relays are generally 5-way relays rather than 4-way, however in the Original part, the pin between R2-1 and R2-2 (relay terminal pin number 4) has been cut off

Physical Plug Identification

The 9 physical plugs that comprise the fuse panel and body wiring is identified as Sumitomo HD Series Connectors. Unlike most other connectors from Sumitomo, they don’t appear to have a modern Yazaki branded equivalent, making them very hard to acquire. Table of part numbers is as follows:
