Load resisters or Load Equlizers

[Denali132]

What is the differance between the 2? And where do you install them under the hood or do you have to pull your headlights out? I have a 2007 Denali. Any pics or advice on how to install would be great, and how long does it take? I ordered a set from Jeff today,
Any help would be great

A load resistor stops or limits voltage from passing while equalizers kind of boost voltage to trick car computers into thinking that bulb is well and alive. They both wire into the positive wiring of your harness, which would put both under the hood.
