I just bought a 03 Dodge Ram 4.7 4x4 with no power options. And the previous owner hooked up a aftermarket deck and it wasn't working. So I pulled it out to find that they cut the harness out of the dash. So I got one out of a scrap truck and tapped it back in with all wires to the correct colours. I then bought the proper harness from Walmart to hook up the aftermarket deck. It now works but when the stereo is on all gauges drop as if the truck wasn't running. Horn don't work as well as the wipers and no bus shows on the odometer. But when I turn the deck off everything comes back and works fine. Also truck runs fine while all this is happening. Can anyone help me?

Truck is not 2500. For some reason 1500 was not available.
