Haikelite MT07S e-switch wiring?

I’m in the process of swapping the driver in my MT07S over to a Lexel driver, and I’m stuck at working out what the connections on the original haikelite driver mean.

Picture of the existing driver connections

On the Lexel driver I have G (Ground), S (Switch), and L and LS for the switch LED’s.

On the original driver I have:

K1 - red wire
K2 -
R - white wire with pen marks
G - white wire
K- - black wire

First light with anything more complex in it that a clicky switch.

Would this be right?

S - red wire
G - black wire
L - White wire
LS - White wire with pen marks
