Wow that took way too long. Here we go... looks like keysense is the green wire (+) on the ignition harness.

Okay, so I guess now my question is what the heck would I run to that to keep the unit from automatically arming when the key is on?

Here's what came with the manual...

Red (two 10 Gauge)- (+)12V Battery
Black - Ground
Pink - Trunk Release (+)12V
Brown - Flash Light (Parking Lights)
Purple - Reverse Light
Red (16 gauge) - Power Window (-)12V
Blue - Side Door (-)
Yellow - Cutoff Control
White - Acc Input
Orange - Footbrake Switch
White - Lock
White/Black - Unlock

The Siren, shock sensor, and LED indicator is prewired and plug directly into the brain. One of the two 10 gauge red wires has a 15A fuse.

Also looks like the yellow cutoff wire goes to a four pin relay. Pin 85 is where the yellow wire goes, then I have a green wire on pin 87 that goes to battery (+), a white from pin 86 that slices into a green from pin 30 and goes to key on (+)12V. I'm thinking that is for the theft feature to cut the engine off in the event the car is stolen.
