Read the small text under the diagrams.
One takes the 12v from the controller and the other gets 12v from an external source.

 

[vedrinec]

yes i know and see that but pin 25 is 12 v in both ways off connecting ,so im afraid that i dont fry controller because you have 12 v on pin 25 and then from converter 12v

It's not gonna break anything if you do it right.
The DC DC shares the same ground as the controller if it isn't an isolated one. Only 12v+ from the brake light is connected to pin 25.

Obviously don't connect 12v+ to pin 11, just leave it empty.

So io dont use pin 11 just pin 25 and pin 6 this is ground on kelly ?

 

[vedrinec]

si it i same if i use ground from controler or dc converter ,because i must it is lamp with low light and high brake light so i must use ground form dc for low light and ground from controller for high/brake light

 

[eee291]

The Kelly is already grounded through the main battery-. So you just need to connect the brake light+ to the Kelly pin 25.

 

[vedrinec]

ok and what goes to minus on light ,does it go minus form dc converter or minus ground form pin 6 that kelly uses as ground ?

 

[eee291]

You could connect the DC DC minus to the frame of the vehicle, like on any other car or scooter.

 

[vedrinec]

do i use negative form dc and connect that to pin 6 gnd of kelly or i dont need to =

Do you have a isolated dcdc or not? This back and forth is tiring.
