viper 5701, yukon, buick

On some GM vehicles, the best +12v constant source is the battery.  Get a small roll of 12 gauge stranded "primary wire" and solder a length to the remote starter power wire.  Might have to run more than one.  Protect from heat, vibration and chaffing enroute the battery.

For the Tach signal, you could also go to a Fuel Injector.  Connect to the "non-common" color wire.  ( Each FI will have two wires. Look at several FI's and you will see that they all share one "same color" wire and each will have a unique color wire. Connect to the most convenient "unique" color. )

Kreg thanks for your help, got everything working except the remote start.

The buick has a key with a code, the remote start works only if I have the key pluged in. Its one of those $ 50 keys that they put in some kind of code, any ideas ? again buddy this would be impossible without your help.

The DLPKGM should be able to bypass your 2002 Buicks' PK3 system.  Are you running in D2D mode?  Did the module program correctly? 

Kregggggggggg done the second alarm is finished ........

I not only want to thank you again and again for your help, but I consider you my friend by now :) This installation would be nearly impossible without this forum and your help. Thanks again. BTW the problem was I was turning the key too fast and the module didnot have a change to read.

Thanks kreg !!!!!

Does the module control the parking lights and door loc/unlock?  Or did you connect the 5701 directly to the car for those items?

I would try reprogramming it and verify the LED responses were correct.  Last try would be switching to  W2W mode.

Another job well done!  Congratulations!     Now all the relatives will be wanting one for Christmas.

The DLPKGM module can't do the trunk.  You have to go directly from the 5701 to the car for that.

TRUNK RELEASE    WHITE/ BLACK (-)      @ BCM, GRAY Plug, Pin 16      It's a (-) trigger so wire and set the Viper accordingly.

Vipers are not my forte.  Hopefully a Viper expert can jump in with the two car / same remote programming for you.
