Video of the boards and my questions

I have a harmar al600 and lift to transport husband’s power wheelchair in my van, it is controlled with an wired attached hand controller. I purchased a compatible wireless remote and control board to add on but it came with no instructions. The seller seems to not have this info either and after hours of searching, that info isn’t available online anywhere. They want people to go to a dealer instead of diy. So I’m here hoping to get some help. Thanks in advance.

 

IF you can discover the maker of the RC system you may be able to get some customer support.

 

Welcome to AAC!

We can try to assist you but we will need more information.
We know that the lift is Harmar AL600.
Can you post a link to the remote controller?

Avoid posting videos. Photographs will be better.

 

What we would require to create a design for the interface between the two systems is :First, information as to the functions controlled by the wired remote control pendant, and second, information about the connections to the wireless control package. This might include pictures of the interface connection areas of that remote control system.
