Question:
Hello, I am looking at this for my 2004 GMC Sierra 1500. Would this work? Or there something better. Not looking for anything real expensive or fancy and I dont want to use a BT device on my phone. Also something that doesnt drain the battery with LED lights. TK78HR

Hey Mike, thanks for reaching out!
In order to install the Tekonsha Prodigy P2 # 90885 on your 2004 GMC Sierra 1500 you'll need the Plug-In Wiring Adapter # 3015-P, which plugs in under your dash. We actually have a pretty detailed helpful article about the installation that I'm linking to this page for you to check out.
This is a proven brake controller that's straightforward and easy to use. It does have an LED display, but that goes to sleep after 15 minutes of no movement of the vehicle, and it would take quite a while of the truck sitting there for the controller to drain the battery. This is pretty much true of every controller on the market.
