After the installation check all wiring routing and connections. Make sure all of the terminals and pins are crimped tightly and are fully seated in the connectors. Confirm all of the connections with the wiring diagram in the installation instructions. If any wires or connections have been modified or shortened, use an ohm meter to confirm continuity through the connectors.
