Connect your vehicles headlight bulbs to FULL BATTERY VOLTAGE for MAXIMUM BRIGHTNESS! At Aspire Auto Accessories, we manufacture and carry our own Heavy Duty Relay Harnesses that fit a wide selection of bulbs commonly found in most vehicles.
This kit is designed to fit vehicles originally equipped without the Dodge Ram Sport Package with 9004 (HB1) bulbs and CONVERTED or is CONVERTING to the Dodge Ram Sport Package with 9007 (HB5) Low Beam Bulbs and 9004 (HB1) High Beam Bulbs. This kit is built with two wiring harnesses one for each side of the vehicle and includes a total of four (4) 30 /40 AMP relays.
This harness prevents costly damage such as melted headlight sockets and burnt wiring. Our Heavy Duty Headlight Wiring Harnesses increases voltage over stock wiring making your headlights brighter and whiter. The harness draws power directly from the battery to the headlights eliminating voltage drops and improving headlight system reliability. All harnesses cover both low & high beam. This harness installs without any wiring cutting or splicing. Choose from 14 Gauge or 12 Gauge Headlight Wires - Our wire is USA made. Don't settle for import wire! Import wire typically has extra thick insulation that makes the copper "under gauge"! Additionally, most import wire we see has very poor quality copper.
Step 1: Select Wiring Harness Gauge
Step 2: Select Power Wire Gauge
Step 3: Soldered Connections
Step 4: Select Batteries Equipped
Step 5: Daytime Running Lights
Unsure whether or not your vehicle has daytime running lights? If your Dodge Ram is equipped with Daytime Running Lights your Daytime Running Lights will illuminate high beam at low intensity.
Additional Information: Connector Type
All connections are machine crimped and shrink wrapped to the highest industrial standards.
Why use a Heavy Duty Relay and Headlight Wiring Harness Upgrade?
Reason #1: To minimize the VOLTAGE DROP in factory headlight systems. Voltage drop lowers the energy delivered to your headlight filaments which reduces their output. Voltage drop is a result of electrical power being run for long distances through thin wires. You can visualize voltage drop by imagining yourself drinking a beverage through a long thin straw (electric energy is the "beverage" and the wire is the "straw").
Reason #2: Using a 9004 (HB1) to 9007 (HB5) Heavy Duty Relay and Wiring Harness Upgrade reduces the current that is handled by the head light switch by a large margin. This reduction in current greatly increases the life of your head light switch.
For example: Your factory headlight systems POWER flows from BATTERY to HEAD LIGHT SWITCH in passenger compartment. When head light switch is turned on, POWER flows back out into engine compartment and then illuminates HEAD LIGHTS. Notice the long distance that power must travel. To make matters worse, typical factory headlight wires are 18 Gauge or LESS. These long runs of thin wires starve your head lights of energy.
ADDING A 9004 (HB1) to 9007 (HB5) HEADLIGHT WIRING HARNESS & RELAY UPGRADE:
Increases the power delivered to your head lights by minimizing the distance power must flow from battery to head lights AND by passing this power through thick, 14 Gauge or 12 Gauge USA made wire (Smaller Gauge = THICKER wire) with the highest quality copper conductor.
AFTER INSTALLING A 9004 (HB1) to 9007 (HB5) HEADLIGHT WIRING HARNESS & RELAY UPGRADE:
POWER flows from BATTERY to HEAD LIGHT SWITCH in passenger compartment. When head light switch is turned on, POWER flows back out into engine compartment and then ACTIVATES RELAYS on the wiring harness. The RELAYS then CONNECT the HEAD LIGHTS DIRECTLY to BATTERY through 14 Gauge or 12 Gauge wires.
In simplified terms, the 9004 (HB1) to 9007 (HB5) Heavy Duty Relay & Headlight Wiring Harness Upgrade is triggered by the head light switch and when triggered, the harness supplies power to the head lights through a more efficient path.
This relay and wiring harness upgrade is one of the most simple and effective ways to improve dim headlights and overall headlight performance by increasing both your low beam and high beam illumination. Perfect for dark roads, off-road, and rural areas!

for anyone with minor mechanical aptitude, this job is a breeze. The harness is practically plug n' play. remember to notch your sheet metal on the inside (closest to radiator) to allow clearance for your 2nd bulb since sport housings use the 2 bulbs.
Great product easy to install and works good
I purchased and installed this 9004/9007 wiring harness along with the Brite Box to convert my 2nd Gen to sport housings. I am throughly impressed with this combo; it has been a significant improvement in light output compared to the original SLT single bulb set up. I had one minor issue during install, Aspire was very helpful and helped me resolve it quickly; their customer service is fantastic. I highly reccomend this product.
Very easy install and the results are impressive! I was able to connect, route and zip-tie the harnesses in less than 10 minutes! The effect is drastic and impressive.
The wiring harness is top notice. Fixed the problem I was having. Makes a big difference in light out put
