Im about to install this system for antilag/2step. Got a question with the options tho.

Im bit unclear with the 10 step retard. It says it reduces timing up to 30degres maximum, but says its used to nitrous switch and high speed runs??

To activate this option you must connect the pink wire to 12v.

Now to activate 2step retard you can only select rpm limit on the 2 step, the wire to activate the 2 step is blue and must be feed with 12v.

Now my question is to activate the 2 step as well as ignition retardation (boost off the line) do I have to connect both of these wires blue and pink to button 12v switch?

Maybe im being bit unclear but those of you who have MSD DIS box will know.

thanks in advance
