haltech Elite 2500 NSP Software, how to wire up in car E. Stop button

hello,

As the title states, I am almost finished re-wiring our whole car with Haltech ELITE 2500 w/ WB2 controller, IC7 Dash and can hub, key pad with LS1 terminated harness but removed the haltech relay/fuse box to install our custom built Jolt Systems relay board with overhead switch panel. Looking for some help/ information as to how to wire in a, in car "RED E STOP" BUTTON that will be mounted to the side our M&M Shifter. Thank you in advance.

I'm not familiar with "Jolt Systems", but let's start with what you want the button to do. Shut down the engine, kill certain electronics, kill all vehicle power?
