Hello, I'm wondering if anybody could help me identify this part on my 5th wheel. It is in a box in the back of the king pin. The box has some wiring and 3 fuses. This part to the right looks to be a contact or solinoid of some sort but I really dont know. The box was damaged and when I move it this part made contact and arced in the box. The part is pulled away from its housing that is still screwed in the box. Any help is greatly appreciated. Thx
