ONNECTIONS
Connections to the vehicle electrical system can be simplified by using the 12 relay
board. Simply install the cab load switches in series between the Total System Manager and
the 12 relay board switch inputs. This installation allows the dash switches to illuminate only
when a load is enabled, giving the operator a quick check of the vehicle’s electrical system
ready status.
