The trigger wire is a power lead to put initial power
to the limousine’s Main Circuit Board. This wire
is always active as long as the vehcile key is in the
on accessory position. This allows the switches to
become live so that you can run the systems on the
board. Without this wire the main board will not be
able to activate. Once the main board is activated the
power to operate the systems is drawn from another
power source.
