I soldered my wires directly to the heated bed after the connector burned up, but the wires still occasionally broke loose from the bed due to stress. I tried a cable chain but it still created stress at the end of the movement. Most of the other options I found required attaching directly to the heated bed or rotating the bed causing clearance issues unless I resoldered everything. I whipped this up in tinkercad and it attaches to the cross brace below the bed. I used PETG to print, ABS should work fine too. You might be able to use PLA if your bed is insulated on the bottom (a piece of corrugated cardboard works great). A zip tie around the end is enough to stabilize the wires and prevent movement near the connections. This is long enough that it may work with the connector attached too but do not have the connector to test.
