I'm trying to find ignition-hot power. There's an empty connector just above the brake pedal that has what looks like always-on power. It has (I think) 12 pins. Black appears to be ground, and orange is +12v. Other pins have nothing on them (as viewed by a voltmeter). Anyone have a diagram that shows the pinout for this connector?

Ignition hot is pink in the ignition switch harness. If you are doing remote start be sure to also power the white wire.

Alarm and Keyless Entry Wiring Colors and Notes
Function	Vehicle Color	Location
Constant +12 Volts:	RED	IGNITION SWITCH HARNESS
OEM Alarm Disarm:	LT. GREEN (-)	INSIDE OF DRIVER'S DOOR AT MODULE
Dome Lights/Superv:	GRAY/BLACK (+)	UNDERNEATH DASH AT COURTESY LAMP
OEM Horn:	BLACK / YELLOW (-)	STEERING COLUMN HARNESS
Power Lock:	SEE NOTE BELOW ***	CAUTION - DATABUS SYSTEM
Power Unlock:	SEE NOTE BELOW ***	INTERFACE MODULE RECOMMENDED!
Trunk Release:	N/A
Alarm Input Wire:	GRAY/BLACK (+)	UNDERNEATH DASH AT COURTESY LAMP
Notes:	*This vehicle uses an extremely complex lock/unlock circuit. To Lock/Unlock, we recommend use of the 23561 Door Lock Interface module, available through DesignTechs sales department at 800-337-4468 . Alternatively, you can wire inside each door for reverse polarity door locks. The 23588 module is easier to install, less expensive, and requires less wiring than the reverse polarity/relay method. Motor Wires, should you choose the reverse polarity method, are Gray for Lock and Tan for unlock. SOME of these vehicles have a switch on the right rear panel which can lock/unlock all doors as a positive trigger system. If so equipped, the wires are Lt Blue for lock and White for Unlock. Connection of the locks without the module is not supported.

I have a 04 trailblazer that unlocks but doesn't lock. We are using the GMDAA. Tried to change ground and power sources, harnesses, and the unit. Also grounded the lock input wire to see if we could manually trigger the arming. But nothing. We are STUCK! I've read another post about how there are differences for different trailblazers?? Any help will be appreaciated!

Tell the Snap-On guy I'm not here!
