Air bags are vital part of a safety system. Never install main unit
in a way which will alter air bag wiring or interfere with air bag
deployment. Air bags must function properly in the event of an
accident.
Before installing, check the location of pipe, tank, electrical
cables and others.

Wiring location must not interfere driving, get in or out from car.
Use electrical tape to insulate the ends of all wires, even if they
are not used. Proper insulation prevents arcs, shocks and fires.
When installation is complete, test all vehicle electrical systems
