I need to replace the seat cushion on my drivers seat, not a huge deal but I have the opportunity to pick up a in great shape electric seat off of another rig. My current setup is full manual, anyone here install and wire in power for an electric setup? I know it will bolt straight in but there is no harness for power so it will be a custom job to get it running. 2001 Silverado 2500HD 4 door.
