sofa bed on chevy 20 van won't raise back to bench , any suggestions how i can fix?

Tryed switch, wasn't working, then tested wires to sofa motor with test light. No power to them, so jumper cables to my silverado, and connected ends to sofa motor, it wa spinning turnbuckles, but they wasn't connected to sofa frame , so unbolted seat to get access to hook up turn buckles, fastened, then afterwards, had to remove seat from van, lay on side, and was able to get it to raise,by using dirrect power from silverado battery, hooking cable end to male seat motor prong, and screwdriver clamped and inserterd into female end.
