• Mount the RSDT using #10 screws. The RSDT is connected between the vehicle electrical system
and the loads to be controlled. The loads may be radios and computers or other electrical loads (lights
and flashers).
• The RSDT terminal marked +BAT must be connected to the vehicle electrical system through a
fuse with a value of 20 amps or less. This connection can be made to a fuse panel or directly to the
battery. If the RSDT is connected directly to the battery the fuse must be located within 5 inches
of the battery's positive terminal. Remove fuse until installation is complete. Use the table below to
select the appropriate wire gauge.

• Loads are connected to the +OUT terminal. Additional protection can be provided by inserting
manufacture recommended fuses for each load connected to the +OUT terminal.
• Connect the GND terminal to a good, clean chassis ground. The RSDT is powered from the
+BAT input and this ground.
• Activation of the RSDT timing period may be automatic by sensing the battery voltage drop when
the engine is turned OFF or by the optional IGN connection to the ignition switch.
• For the ignition switch activation option, connect the IGN terminal of the RSDT to the ignition
switch terminal that goes to zero volts when the engine is turned OFF.
• The GND and IGN connections carry very little current (< 0.1 amp). Wire gauge is determined by
mechanical suitability.
• Use #6 (GND, IGN) and #8 (+BAT, +OUT) ring or spade terminals for connection to the RSDT.
Note - When using the ignition switch option, the RSDT period will not start if the engine dies.
