Installation
Installation must be done with the harness disconnected from the Input Expander and with the battery disconnected from the vehicle. It is
very important that the wiring harness is as short as possible and any unused wire must be cut. Never roll any leftover wire in the harness.
This will avoid any interference issues, common in any electronic equipment.
The harness must be protected from contact with sharp parts of the body and frame that may damage it and cause a short circuit. Watch
out especially when going through holes, always use rubber grommets or similar protections. In the engine bay, route the wires away from
excessive heat and any moving parts. Insulate the wiring harness whenever possible.
