I tried to use them on an electronic burner control with spade terminals and the wires didn't hold up well. The plugs were loose and wobbly, and the cable came loose. I used my crimping tool and still couldn't make a secure connection that I was comfortable with. I ended up going the other way and using factor flag connectors that I attached to my wires. I can't give them a rave review because I've had trouble using them and attaching them securely to my wires.
