Shooting Jack

I have just found the 4 Din plug to supply power to the camper. I did not get a cable with it so need to know how to wire it and what each pin is for. Is there a wiring schematic available for a Shadow Cruiser 7. I finally got the refrigerator lit but it's not cooling and flame stays real low. So far I can't get the heater to kick on. It has auto light but fan will come on after about 30 seconds but no fire. Thanks for any help as I'm a little frustrated right now.

I just purchased a used Shadow Cruiser 7 and don't have any paperwork. I would like to start the refrigerator on electricity. What should the settings be on the converter. One setting is batt or ac. It has two relays/breakers and I forget what the other switch is. Help please as I dont' want to mess anything up. Thanks
