If you use a 3 step or even just a 2-step you need a toggle switch in line on the output of the relay that you turn on AFTER burnout. The line lock still works in the burnout and with that switch turned on now the line lock and rev limiter work with the foot pedal switch but only after activated by the line lock button. I use the same method in both my stick and auto cars. I have a youtube in car video also. As far as the 3 step MSD 7al 3 box goes, launch and burnout have their own rev limiters but LAUNCH always takes precedence over burnout if both are active at the same time, which they always are in my car on the launch because linelock controls burnout for me and foot pedal controls launch. If you don't want or need a burnout limiter just pull the chip out.
