Fan wiring (ground switching relay)
The grounding output in Figures 2-4 can also be connected to a toggle or
momentary switch, depending on the desired function. For this application, one side of
the switch would need to be grounded and the other side would then connect to the white
wire of the single relay pack to act as the grounding output.
For power door locks, it is convenient to use a dual relay pack and control the
drivers side off of one relay and the passengers side off of the second relay. Ground
switching dual relays can be connected as shown in Figure 5 to operate drivers and
passenger side solenoids or motors. Again, the grounding output can be a momentary
switch with one side connected to ground.
FIGURE 5
Dual (ground switching relay) relay wiring
For power windows, a dual relay pack is also convenient to obtain up and down
motion. Figure 6 shows how to connect a dual relay pack to drive a power window
motor. The ground-at-rest switch shown supplies 12V to the window motor when
pressed so it should have appropriate current ratings if it is being used. The dual relay
pack can be used for a power trunk motor connected in the same fashion as the power
