VMI Fuse & Relay Panel Instruction Manual

This guide provides fuse and relay layout and connection instructions for VMI harness configurations. Proper use of relays and adherence to wiring specifications is critical to ensure safe and reliable operation.

Important Safety Notice

This harness requires relays with internal suppression resistors. Do not use relays without internal resistors as doing so may cause damage to diodes, LEDs, and resistors.

Relay Orientation

Correct Orientation:

- Terminal 30 -> 87A

- Terminal 85 -> 86

Incorrect Orientation:

- Terminal 30 -> 87

- Terminal 85 -> 86

Relay Identification

Relay B - BTSI (Brake Transmission Shift Interlock)

Relay C - Power Supply

Relay D - Ramp Out

Relay E - Ramp In

Relay G - Kneel Up
