96 gmc sierra keyless entry with viper

I am trying to wire my viper 211hv into my sierra and cannot get it right and the violet/black fuse keeps blowing. i understand that i have the 5 wire system and that the 211 has built in relays. I quick spliced the wires as following into the harness the plugs into the drivers side door; GREEN/ black - light blue WHITE/ black - grey blue/black - white BROWN / black - tan Could someone please help me?

Two door or four door? Just making sure, the to door is Type C and the four door is Type A. Either way, you can follow the correct wiring diagram for the 211HV 6 lock relay wires found in the Directed 451M Install Guide ( in the Downloads Section ). The Relay Pins and wires colors are the same. If you post back with the door info, we can even make-up a wire connection list to help.Soldering is fun!

2 door.

H1/5 GREEN/ BLACK LOCK #30 COMMON OUTPUT cut Light Blue Lock wire - lock motor side H1/6 WHITE/ BLACK LOCK #87a NORMALLY CLOSED        cut Light Blue Lock wire - switch side H1/7 VIOLET/BLACK LOCK #87 NORMALLY OPEN (INPUT) through fuse to +12V constant H1/8 BLUE/BLACK UNLOCK #30 COMMON (OUTPUT)        cut White Unlock wire - unlock motor side H1/9 VIOLET UNLOCK #87 NORMALLY OPEN (INPUT)        through fuse to +12V constant H1/17 BROWN / BLACK UNLOCK #87A NORMALLY CLOSED  cut White Unlock wire - switch side The 451M Install Guide gives a pretty good description on how to test the wires, etc.Soldering is fun!

so motor side is technically the wire that goes to the door? Thanks!

Im pretty sure i hooked it up just as you said and i still have nothing and the fuse still blew. i even tested for the switch side, I have done ALOT of automotive wiring but this thing is just kicking my ass. What could i be doing wrong?

Just noticed this note from Bulldog Security :

NOTE #2: if vehicle is a 2-Door it is a TYPE C door lock system, if vehicle is a 4-Door or if it

has a FACTORY KEYLESS ENTRY System it is a TYPE A door lock system. If vehicle

is equipped with a FACTORY KEYLESS ENTRY the vehicle is a TYPE A System.

If your truck came with Factory Keyless Entry, then you have Type A locks, even on a 2 Door truck.

It is also possible you have a wrong wire.  Download the Directed Tech Tip 1041 document.  It has some more

info on Door Lock systems.  See the notes in the Type A Locks for testing and differentiating.

Here is another tip posted on the Forum a while ago on Type C locks :

Lock Motor wire info :

Easy way to tell which side of the cut wire is the switch

and which is the motor, is to cut the wire and then press

the button. If it shows 12v it is the switch side of the

button you just pressed.  Some times it isn't always easy

to tell which end goes to the switch and which side goes

to the car.

It didn't come with factory keyless entry so it's a c. I swear I had it right but I will check again tomorrow.

Alright so i figured out that i had the motor/switch sides flipped, idk why i wouldve done that. so i pulled all connections off and tested for 12v again and got it wired up exactly how you said; WHITE/ black - light blue 12v side BROWN / black - white 12v side GREEN/ black - light blue 0v side blue /black - white 0v side violet & violet/black - constant 12v red - constant 12v black - ground yellow - ignition 12v This time the fuse doesnt blow but nothing works Do i need the 2 external relays for this system? or is there something i am missing here. Im feeling really dumb over this!

Strange problem.   

First, hook up the Parking Lights.  It might help with troubleshooting.  H1/10 White wire to :

PARKING LIGHTS ( + )  BROWN (+)  @ HEADLIGHT SWITCH or FUSEBOX  Make sure the 211HV's internal Jumper is set to (+) Parking Lights.

The 211HV has internal relays so nothing more should be required for this install.

Re-verify your Chassis Ground connection and also that the 211HV's H1 connector is fully seated.

The Violet and Red power wires must connect to a +12V source capable of 20 Amps.

Does the 211HV have a relay click sound when you press the Lock or Unlock button?  The Parking Lights

should flash, too.

Guess at this point I would get some 10 Amp fuses and a couple of jumpers.  I would test the White and

Light Blue wires manually to verify that I had the correct wires and that they can control the locks.

Initial test :  Re-connect both lock wires back to normal.  Verify the trucks door buttons function normally.

Use a DMM, set to 20V DC, Black lead to chassis ground, Red lead to either lock wire.  Press the doorlock  ( or unlock ) button and watch for a +12V signal.Next cut the Light Blue Lock wire.  Press the door unlock button.  If the doors unlock, you have Type A locks.

First test.  Re-connect the White and Light Blue wires ( either by twisting the wires together or a jumper ).

Verify that the factory door lock buttons function properly.  Take a 10 Amp fused jumper from a +12V constantsource and briefly touch it to either the White or the Light Blue wire.  With Type C locks, you will blow the fuse.With Type A locks, the locks will either lock or unlock depending on which wire you touched with the jumper.If this operates the locks, re-wire the 211HV for Type A locks and you are done.

Second test.   Separate the Light Blue lock wire.   Touch the fused jumper to the Motor side of the wire.  The

doors should lock.  If the fuse blows, try the other side of the cut Light Blue wire.   Reconnect the Light Blue wire and try the same routine with the White wire.  At this point you know you have Type C locks and whichside of the cut wires are motor and switch.  Wire the 211HV accordingly.

Soldering is fun!
