Yes, I used the SLP Brake Control kit, 0053916. The switch I did myself, just found an aircraft safety switch on Amazon. I think I just replaced the switch that came with the SLP kit. You can probably do the same with other kits.

Padre - Did you use a specific kit when you installed your line lock? I'm looking to install a set up similar to yours with the master arming & activation switch because I do not want a momentary pressure button.
