Electrical wires in water

First you swim forward then you will see a ladder to climb. Then go left and hit b button to shoot knives. Hit all 3 1 short 1 and 2 long ones just be fast. If you are good you can hit one that is far away,but I don't recommend doing that just leave b button and swim to next ladder best if second water has not started to flood area. Repeat process but get big wire first then hit one that is straight and far away takes trial and error. Then quickly hit short wire that is close to water. Swim to exit

Swim forward till you see a ladder climb up the ladder then go left and hit b button on context sensitive button. Use knives to hit 3 wires 1 short and two long in any order. If your are good you can hit a forth wire,but best to just ignore it. Best situation you get all 3 wires before another cutscene. Swim to next ladder climb upnit and jump onto b button throw knives at big wire then hit one that is far away takes practice,patience, and luck. Then hit small wire thatbis close to water..
