MSD 6425 and 2 step?

[Jeff Stout]

I wired in a 2 step on this box. I connect 2 step between grey wire and tach and cant get it to work. Blue wire connected to button on brake pedal Im lost. Help!

You should have 4 wires from the 2 step. Grey tied in to tach and Ign box, Red to 12 v, Black to ground and Blue to switched 12v ( normally open ).

Was it a new 2 step? No red light when activated by 12v on the blue wire?

That is correct. It still wont activate. 12v from brake button to blue wire when activating.

???? Did you check with a volt meter that you are energizing it with 12 volts? You maybe losing voltage if your going through a brake light switch. That's all I got.

Check things out again and now it works. Thinking new button is suspicious. So damn hot out here making it tough to work.
