Need help wiring Fleetwood Caribou to truck

[Reconjarhead]

Looking for info on how to wire a 1993 Fleetwood Caribou 8.6 cabover camper to my 01 Dodge pickup. The camper has a 3way fridge and does have one battery installed in the camper. There is a converter for 12v power when plugged into 120v.

I tried once to wire the 7 pin as a standard RV plug and it smoked the 10Ga wire from the truck immediately, my guess was a direct short to ground.

Looking at the plug it appears to be a standard 7 pin rv style plug. where it enters the camper there are only three wires. There is a Black 10Ga which is connected to what looks like a small relay under the counter of the camper (my guess is an isolator relay). Second wire is white 10 or 8Ga which goes to a wire nut with two other whites, One goes towards the fridge and is 10 or 8 Ga and the other is a smaller white wire not sure where it goes. Last wire is a green 14 or 12 Ga.

All I'm trying to do is get the running lights on the camper working and have a charge line from the truck while running. I did install an ignition controlled isolator on the truck.

I don't think anything has been changed from the factory configuration on the camper wiring but I haven't had much luck finding what the standard wiring is for the plug.

Any help would be much appreciated.

Thanks for your service.
The black wire should be 12v+,the white should be 12v- and the green should be camper lights. That small relay under the counter is a circuit breaker. The short that let the smoke out should be before that circuit breaker.
I hope this helps

That did the trick, thanks. I think the idiot (me) who installed the plug put it back together upside down which reversed the white and black when it was plugged in
