Used to get power from the 12v pads on the Moza wheelbases, I used the screws, springs and nut from the horn connector on the Kyostar through the holes to face the pads.
I then cut an old pen spring in half, soldered that to a red and black wire each, and with the spring on the nut side, routed through and screwed into the quick release.
Will upload additional photos for information later.
