I found that my VSS doesn't always give a signal to my ECU so when there is no signal AEM gets a reading of 0MPH and the two step stays activated. I want to rig it up to a button like I had with my MSD.

My question is what pin number on which plug do I wire it into and is it just a normal power in one side and the other wire to the ECU?

 

If you look at the Two Step setting you can make it turn on when a certain wire is grounded. Look in the drop down menu and you'll see all the available wires. Then go to your pin diagram and wire a ground switch to it.

 

yeah what he said chad you can ground it out or send a break a 12 volt signal depending on which out you use

 

check your AEM files and they should tell you what pins are what
