DHP perfomance shift and GT

Okay, just got a DHP, but not installed yet. Is performance shift function automatically enabled as a defualt in the DHP version 1 or do I need to hookup a switched ground wire to the pcm ?
Again this is for a 3.8 GT not GTP.

Thanks for any info..

from my understanding the dhp for a gt is always operative, but i have limited experience in that background.

yeah ts always operative in a gt
