Based on your comments, I presume you have the Stone Bennett Air Shifter. If it is like mine, the red and white wire powers the shifter at the transmission, the orange and white wire powers the display and the blue wire goes to 12 volt DC. These wires should be found at the round 16 pin AMP connector at the dash. On mine, the electric shift power blue wire goes to the chassis fuse panel on the firewall in front of the copilot seat slot #2. I would check that fuse first. Just because it looks OK doesn't mean it is passing current. Pull the fuse and clean the contacts on the fuse holder.
