It plugs in to the back opf the pcm i think there is a plug in it just make sure it hasnt gotany dust on it also make sure you disconnect the battery. Diablo products always make vehicles run rich especially at idol if i was you i would try and sell to someone and getthe sniper tuning software. The pcm is behind the passenger side kick panel you will probably have to take it out to plug in the chip. Make sure you have the switch or it wont do much good.

I was unaware that you used the chip AND predator together. I thought the Predator was just a better version of the chip.

In any case, taking the chip out is a GIANT pain in the ***. I just did mine a few weeks ago (changed it for a Sniper and it was a great decision).

After you remove the kick panel, the PCM is vertically flush against the body. It's held in by an annoying retention clip, and packed in there by a metal bracket.

I could remove the PCM by simply unseating it from the bracket, but to get it back in I had to remove the outer metal bracket and shove it up there with all my strength. It took about an hour, but mostly because I tend to fail at "finesse" stuff like that.
