connecting 556cw to 562t

I have a DEI 562T in a 2007 Jeep Liberty. I am using the DEI 556CW sentry bypass module.

Currently, I have the red wire on the 556C to constant (+) power. I have the blue wire (-) going to the relay satellite ribbon cable, the violet wire (-200mA starter output).

I figured this would be correct as it'd trigger the unit when starting, then shut off. The vehicle doesn't like this and shuts itself down. If I manually ground the 556C, it works perfectly.

So, which wire should I use for the ground? Should I use the blue (-) status output or the pink (-) ignition output, or some other one?

Thanks!!!
