I am new to RV's and Campers. I just purchased a older model Holiday Rambler "70s'. It doesn't have any of the cables to hook up the electric. I purchased a connection online but it doesn't match up to my camper I haven't been able to find the right one. I have attached a Photo of my hook up on the Rambler. The L shape pin is on the wrong direction compared to all the cables I can find online. If anyone with more knowledge could point me in the right direction to get the cable I need.
