Changed over to 3 step from 2 step! Questions : What module # for launch ( tranny brake) rev limiiter and burnout? How do you folks.test it before going to track? ........ Called MSD ! #1 Tranny Brake starting line launch #2 Rev Limiter #3 Burnout (biue wire) Have to check with low RPM chip! Wish they would address this in instructions! I am one of those people who has to have a picture!

From looking at the instructions for one, it appears it is what you want it to me. Different wires activate different modules. So if you want one to go to the line-lock and the other to go to the trans brake that is just how you wire it.

For testing I would just get a very low RPM module(s) for testing.

I have no experience with these and did not stay at a Holiday Inn Express last night.

#2 is the default high side limiter. It is active when no voltage is applied to the other 2 wires.

#1 is active when 12v is applied to the red wire.

#3 is active when 12v is applied to the blue wire.

Test it with a 3000 chip in each port as you apply voltage to the applicable wire(s).
