Holley H840 Retrobright Switched Ground Harness

Rock Solid Hitch

Solid hitch with serious strength and clean powder coat, heavy to lift, but installs easy and tows perfectly!!

Great Shipping

Shipping was quick and on time - exactly what I needed for my small-block build - would buy again for sure

Perfect Fit Mats

Weatherbeater mats fit my work truck perfectly. Dropped them in and nothing moves. Truly a great upgrade

Sleek Visors

Window visors look incredible and feel durable, install was simple. Zero wind noise on the highway!

Leveling Success

Leveling kit components were well packed. Instructions lacking, but online videos helped. Rides level now and feels planted.

Found Single Lifters

Found single lifter pairs in stock here when others required full sets, fast shipping got me racing again, hell yeah!!

Desert Series Bumper

Rear bumper upgrade looks better than factory plastic. Install was easy, and functionality is miles ahead. Highly recommended.

Lomax Fitment

Tonneau cover fit is excellent. Clear instructions and a smooth install. Delivery to my door was super convenient

Next Day Turbo

Turbo arrived next morning and matched description. Bolted up cleanly and truck is back to full power.

Legend Grille Guard

Husband’s birthday grille guard is rock solid, looks sharp he loves it so much!!! Thanks again

Shipping Protection Helped

Customer service handled a damaged shipment immediately. Refund was painless. I’ll shop here again.

Easy Exhaust Install

Exhaust system installed in two hours on my first try. Perfect fit and the sound is pure joy.

Description_MKT	Many Toyota vehicles will have a switched ground that doesn't allow the RetroBright headlights to work right out of the box. This harness is designed to switch the ground back and then the RetroBright headlights can be plugged into this harness. We wanted to expand the great RetroBright experience to the switched-ground vehicles so more people can enjoy the safety and beauty of RetroBright LED lighting.
