DIY Wire control motorized BED to Wireless Control

DIY Wire control motorized BED to Wireless Control

I have converted wired controller Motorized Bed to wireless.
See how to do it here
In my case you have to buy from ebay or Amazon the remote control units, see links below
after disconnecting the remote control I have found 4 wires:
Red,Green, White and Black
I have noticed the following:
1. When not moving anything the RED Green and Black are all shorted together
2. When lifting Motor Up: Red and Black are shorted, and also White and Green are shorted
3. When lifting Motor Down: Red and Green are shorted, and also White and Black are shrted

– so I have used the relay board to do the same, watch the video to see how
