Review: If you have a GMT800, get this. - I bought 2 of these, one for a 2004 Yukon and one for a 2005 Silverado 2500HD. Installation takes 2 minutes, it uses all of the wires unlike the free method which puts all of the amp draw on a single set of wires, which is a fire hazard. They worked as advertised and are fantastic. Half of my driving is at night so any improvement in visibility is definitely welcomed. This product is awesome and I'd recommend it to anybody with a GMT800.
Review: Fits perfectly and works well! - I installed this board in 30 seconds and greatly increased my nighttime driving visibility. Combined with LED lighting, it’s amazing!
