I bought a cheap RC Submarine. Similar to the cheap RC Helicopters it's charged via a cable from the Remote Control. The Remote Control is powered via 6 AA Batteries. --> Here's a picture of the Charging Setup LINK

Question: I lost the charging cable and since it's a cheap device I'm not able/willing to reorder one :-). But since I'v got the correct type of connector for the Remote Control Site, I was wondering if I can just solder one with some jumper cables that fits the port on the submarine site. If one of you could tell me of those 4 pins on the submarine is + and -. I think there are 4 Pins to submit the charging state to the remote control (light goes of if fully charged). Is it feasible to just connect two Pins (+ and -) to the charger and ignore the other two?

On the Submarine Site, the charging port consists of 4 pins. Here's a picture:

By closing the hold the pins connect as showing in the picture.

Additionally, here's a close up of the black framed part in the upper picture:
