6) Install new Vertical Doors Inc. system:

For the Vertical Doors hinge to sit flat against the apron, you might have to cut, or hammer flat, a portion of the apron. On some vehicle it creates a better finish if you make a plate to cover the modified area and either weld it in place or fasten it via screws/rivets. The new Vertical Doors Inc. system should sit flat against apron to work properly.

10) Modify factory wire loom:
To be able to open and raise the door, cut the factory wire boot in half. Add wire loom to protect exposed wires and wrap with a cloth anti friction wire harness tape.
You may need to remove the door panel to gain extra slack. Release the clips holding the harness and pull it towards the front of the door. In some vehicles, some wires may need to be extended, but you should not cut and extend all the wires. Once you pull all the slack in the harness you can, then identify which wires need to be extended. Wrap the wire harness with tape and secure with zip ties.
