Accessories Installation

Accessories are where most installs get decided. None of this is hard, but picking the wrong harness or finding out your leads are three feet short is the difference between a Saturday and a weekend. Here is what each part is for and when you actually need it.

For the lights themselves, see the rock light guide or the wheel light guide.

Which wiring harness do I need?

Two sizes, and the answer is usually the smaller one.

30A · 14 gauge - $55. The right harness for almost everyone. Choose this if you are running a set of rock lights, a set of wheel lights, or both on a single vehicle. It carries a standard install comfortably.

40A · 10 gauge - $75. Choose this for larger multi-zone builds, more than one full set of lights, or several zones running off one harness.

Either way you get a relay, switch and fuse, and one lead carrying both the positive and negative connection. The wireless remote gives you on/off plus six strobe options. More detail in Rock light wiring 101.

Magnets or bolts?

Worth deciding before you start, because it changes how you mount everything.

Magnetic mounts mean no drilling into the frame. Each set includes the magnets and hardware for four rock lights, countersunk screws and lock washers included. If you are not willing to put holes in the truck, this is the answer.

Bolt-on is more permanent and better on a truck that sees real abuse. Magnetic vs bolt-on mounting goes through the trade-off properly.

Do I need extension wires?

Only if the supplied leads will not reach. A set gives you two 10-foot extensions for the front wheels and two 20-foot for the rear, which covers the run to the front of most trucks. They are plug-and-play, no hardwiring, no cutting, so they keep the install reversible.

If you are wiring something custom rather than extending a kit, the 50ft 2-pin 16-gauge spool is the better buy.

Replacing something

Strips are sold individually, so count what you need before you order, a quad row set is four strips per wheel, not one. They plug in and secure to the wheel ring you already have.

Brackets come 16 to a set, which is one full set of wheel lights. These are the stainless steel ones with 3/16" predrilled holes; they replace the older aluminum brackets.

One warranty condition worth repeating: use the supplied nuts and bolts. Rivets and self-tappers back out over time, and using anything other than the provided hardware will result in a denied warranty.
