Alarm and Keyless Entry Wiring Colors and Notes
Function	Vehicle Color	Location
Constant +12 Volts:	Red or RED / White	Ignition Switch Harness
OEM Alarm Disarm:	Lt Green	At Module Inside Driver Door**
Dome Lights/Superv:	Gray/Black	At Light Under Dash
OEM Horn:	Black (-)	At sSteering Column Harness
Power Lock:	See Note Below	*
Power Unlock:	See Note Below	*
Trunk Release:	N/A
Alarm Input Wire:	Gray/Black	At Light Under Dash
Notes:	*This vehicle uses an extremely complex lock/unlock circuit- basically the same system as the 2002 TrailBlazer. 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 23561 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.

Easiest Tach on the new GM trucks is pop out the instrument cluster, 4 7mm screws, grab a white wire. It's the onlt Tach for the diesels. Steve

i tried the odd wire on one of the injectors for the tach wire. i held the valet switch and it stayed lit which indicated it had learned the tach. now the problem is it will crank over when i hit the remote starter but the engine will not fire up and run. i installed the dei passlock2 bypass module. im pretty sure that i wired it up right. i cut the yellow ignition wire and spliced the yellow to the wire going towards the key and the yellow/black going away from the key and the black wire to the black wire. what else could cause this condition? thanks.
