Connector/Breaker in Co-pilot rear seat compartment

[Sigi]

I'm converting my 2 seat truck to 4 seats and found this 2 pin 24V connector in the right rear footwell. It is live. There is a also a breaker behind the panel accessible behind the battery compartment. What was this connector used for? How do I find the mating connector/plug? Might be a good way to attach a charger.

Connector to HMMWV 200 amp umbilical !!NOT slave cable plug!!

(edited) To clear up the confusion, this post is me trying to share the part numbers I found related to the umbilical cable plug in the rear passenger footwell of the heavy variant HMMWVs (M1097, M1123) for anyone that might be looking for them. I found part numbers, and listed them below, as...

You follow the cables on the other side of that plug and disconnect them.
Leave the circuit breaker with red button alone. It is for the transmission.

What does it do for the transmission?

It's a circuit breaker. If a wire shorts out, it's supposed to trip before you burn up the whole truck.
It's just the wire/breaker through which the transmission control module gets it's power. Without it you're stuck in 2nd gear limp mode.

Thank you, Coug. You guys are awesome. I suspected the breaker was for the transmission ECM. I'll leave the umbilical cord socket alone. The connecting plugs are pretty expensive. It will be simpler to connect the charger to the slave plug.

lots of options on how to keep these charged.
Personally I like the NO.CO GEN5X2 marine battery charger. Hardwired to each battery; it charges them independently.

I was lucky when I bought my plug that someone was selling a couple used ones for pretty cheap. Haven't seen any for sale like that since.
