Dual Power Window/Power Door Lock Relay Module

This module is perfect for power windows or power door locks.
Example of uses: You can mount one inside your car and operate 2 power
windows. Add another one to do power locks.
Or you can install one in each door and use one part for power windows
and one part to do the power locks for a simple install that would only
need a hot and ground wire ran in the door.
Wiring:
12v goes to 12 volt source. 14-16 gauge wire
Grd goes to ground. 14-16 gauge wire
M1 and M2 connect to the window motor. Polarity doesn’t matter now.
S1 and S2 goes to the switches. They are triggered by 12 volts.
Test the windows or door locks. If the switches are backwards then swap
the S1/S2 Wires.
The module is pretty simple. Voltage on the S1 makes M1 output 12 volts
and M2 Ground. Voltage on S2 makes M2 output 12volts and M1 ground.
