This document details the installation process for KC HiLiTES relay wiring kits designed for two lights. The kit includes a complete harness with a relay, screws, wire ties, a wire splice connector, and an optional switch with a panel. The instructions emphasize proper wiring connections to a 12 VDC battery and chassis ground, as well as considerations for aiming lights according to their intended use – fog, driving, or long-range off-road applications. A 23-year warranty is offered, with details available on the KC HiLiTES website.
Kit Contents
The KC HiLiTES relay wiring kit for two lights includes the following components:
- One complete harness with relay for two lights.
- Five screws.
- Six wire ties.
- One wire splice connector, intended for use with the white wire.
- One switch with panel (optional, for ½” hole mount).
Installation Preparation
Prior to commencing installation, users are advised to determine the mounting locations for both the lights and the switch. The relay should be mounted close to the battery, ensuring the terminals face downward. It is recommended to remove the relay from the harness before installing the power wires and then replace it upon completion of the wiring process.
Wiring Connections
The harness features several color-coded wires, each serving a specific function:
- Yellow Wire: This wire must be connected to the (+) positive post of the 12 VDC battery.
- Black Wire: This wire requires connection to a (-) battery or chassis ground.
- Brown Wire: Grounding this wire activates the LED on the switch.
- White Wire: This wire must be connected to a (+) positive 12V source, which can be either directly to the battery or to an accessory fuse. It is explicitly stated that the white wire should not be spliced into the yellow wire.
- Green Wire: This wire is designated as the load supply.
Switch Integration and Lighting Types
The white wire’s connection point depends on the type of lights being installed and applicable state regulations:
- Fog Lights: For installations requiring fog lights to be switched with low beams, the white wire should be connected to the low beam hot wire using the provided splice connector.
- Driving Lights: In states mandating that driving lights be switched with high beams, the white wire should be connected to the high beam hot wire using the provided splice connector.
- Low Beams: The white wire can be connected to the low beam hot wire with the splice connector.
- High Beams: The white wire can be connected to the high beam hot wire with the splice connector.
Relay and Fuse Specifications
The relay within the harness operates in conjunction with fuses to protect the system:
- Battery Fuse: A 20/25A fuse protects the power supplied from the battery (yellow wire).
- Switch Fuse: A 3A fuse protects the power supplied to the switch LED (brown wire).
The relay itself features the following terminal designations:
- 85
- 86
- 87
- 87
- 30
Light Aiming Guidelines
Proper light aiming is crucial for optimal performance and safety. The documentation provides specific guidance based on the type of lights:
- Fog Lights: Fog lights should be aimed so that the top cutoff is below the center of the low beam.
- Driving Lights: Driving lights should be aimed approximately at the same level as the high beams.
- Long Range Lights: Long-range off-road lights are not legal for highway use and should be mounted to maximize visibility at a distance. Users are instructed to aim the lights before securely tightening them into position.
