dei 451m blows fuses-1993 dodge dakota

Hey y'all. spent the afternoon on it! And... It's working!! I appreciate both of your help & advice It was greatly appreciated. I ended up wiring it up with the passenger side, but "rigged" it where the DEI unit is under the driver's side dash. Added wires to go in the dash to the other side. (Tested it twice, so it's all good.) I actually think this is the main switch? The wires from the switch on the passenger door, split offs at the door harness (one going to the other side, one going to the passenger motor). So, after 18+ hours, it is all hooked up and ready to roll. Monday I will be taking my dash BACK apart Somehow my radio wire was unhooked! Oh well. God bless you both. Y'all were a great help!
