The original Meyer Touch Pads used the round black plug, and if you have one of these, you'll need to purchase this adapter so it can plug into the new, square white 6 pin plug on the Meyer Touch Pad 22154 control.
Can be used on all Meyer and Diamond lift units except V-66 and E-68. Can be used with the Meyer Classic, EZ Mount and Diamond MD II mount set-ups.
This Harness Adapter 15766, can be used as a square to round OR round to square, depending on the harness connection to your Touch Pad connection.
