07 gmc sierra classic 2500hd diesel

I am thinking of installing a viper 5704 for a friend of mine on an 07 gmc sierra classic 2500 hd with a diesel engine. I am a mechanic but have never done a remote start system. Maybe I should run from it, but thought I might enjoy the challenge of it and help a friend out. What do I need to know? In my research it looked as though I needed another module to run door locks etc. I ordered a dei 555lw. Is that really what I need? Also I would appreciate any wiring diagram help you can give along with any advice. Thanks!

It would require far less wiring with a DB-ALL2 although more expensive. No key lost.
You must purchase it pre-flashed with the software to match your vehicle.

Test before boxing up.

I'm doing an 05 next weekend which I believe is same truck ill take some pics for you. I use xk09 and it makes for a simple install

Ok thanks guys! I'll wait for those pics pentavolva.

Should be similar to this

Ok thanks pentavolvo! I'm sorry I told you wrong in the first post. I actually got a dei 456g instead of a 555lw. Will that work for the door locks and security on this pickup?

One thing to keep in mind on the diesel pickups is that you must hook up a tach wire. For whatever reason on the 05-07 GM diesel pickups, the alternator doesn't kick in unless the battery is below 12 volts. This had me fooled on the couple of trucks I did. The 08 and up models do not operate like this.

Thanks for ur help! I bought a dball2 with software installed for my 07 Sierra Classic and finally got it put in. Door locks work fine but no remote start. I'm getting an error code that has to do with the turbo timer? I did not hook that wire up on the remote start. Is that necessary and what would I connect it to?

Assuming the vehicle is auto then reprogram it for automatic, level 3 feature 1 option 2.
If manual you didn't enter manual transmission reservation mode, see the owner's handbook.

Ok. Here is how I have the wires connected. Remember, I have an 07 GMC Sierra 2500 Diesel with an automatic transmission. I am installing a Viper 5704 remote start and using a DBALL2 in DRD mode(I believe) with it.

1. This is how I wired it up with one mistake I noticed just tonight. I had H2/24 on the 24 pin connector of the viper going to pin 3 of 12 pin connector on dball2. I need to fix this like I have it listed above.
2. Right now the remote start will not work. Door locks work fine. Do you see anything that could be the cause of no remote start? I did get it to remote start once by turning the ignition to run and then pushing remote start button, but it would not shut off with remote.
3. Do I need to wire in a relay for the 2nd accessory brown wire near ignition harness?
4. My alternator is currently not charging. Could the brown 2nd accessory wire not being connected be the problem?
5. I have programmed it for automatic transmission, and to use the wait to start light as I have it wired that way.
I am a total rookie at this! If you have questions on what I wrote here please ask and I will do my best to clarify. Thanks in advance.

Did you even notice my last post?
Also yes to relay for second ACC.

OK.  Going by your wiring, you are going in W2W mode.  This means your are making hard-wire connections between
the Viper and the DB-ALL2.  It also means there is no need for the D2D harness to be plugged in / used.  However, you
did not list the +12V and Ground connections on the Blue 14 Pin DB0-ALL2 connector.  These must be made in W2W
mode.

First an omission.  H2/17 Hood Pin is an important safety feature and is used to monitor the hood for alarm purposes.
With the Hood Pin installed, you will not be able to mistakenly remote start the engine while you are changing your oil
and the hood is up. 

Secondly, the DB-ALL2 does not monitor the rear doors of the truck.  You didn't mention if you had a two door, four
door or extended cab truck.  If you have a four door truck, you will have to hardwire the door trigger wires to the Viper.

While it is probably not your problem, I would power the the trucks Brown ACC2 wire during a remote start.  You will
need a 30/40 Amp SPDT relay and a fuse holder w/ 30 Amp fuse.  Here is the wiring :
Relay Pin 85 to Viper H2/22 Orange wire
Relay Pins 86 and 87 to +12V constant through 30 Amp fuse
Relay Pin 30 to Sierra Brown ACC2 wire
Relay Pin 87a not used

After everything is connected / soldered / insulated, there is a sequence that should be followed.
1.  Set all the need Viper programming options.
     A.  Transmission Mode = Automatic   Menu 3, Item 1, Option 2
     B.  Engine Checking Mode = Tach    Menu 3, Item 3, Option 4
     C.  Flex Relay Function = ACC2   Menu 3, Item 8, Option 2
The rest at Factory Default should be OK at this point, although some fine tuning might be required.  Programming
the Viper with the remotes can be tricky and there is no way to verify the setting change.  Many people have had a
difficult time getting the Viper in to Automatic Transmission mode.

2.  Next, perform the Viper Tach Learn process and verify good results.

3.  Then perform the DB-ALL2 vehicle programming and verify good results.

Test the locks and Viper alarm functions.

Try a remote start.  Remember that the Viper will bring up the ignition circuits and wait until it sees the Glow Plug
signal to crank the engine.  If this doesn't work properly, you can try setting the Viper for a fixed wait time of 15
seconds.  Menu 3, Item 9, Option 2

Remember to use the Viper error reporting system functions to help identify the problem area.

Soldering is fun!

@howieII-Yes I did notice ur last post. Thank you! That's why I mentioned at the top of my last post that it was an automatic, and in point # 5 I mentioned that I had already programmed it for automatic....Thanks also for confirming the relay for second accessory. I'll get it done.

Thanks for the info kreg! I'll see what I can do.

OK, follow Kreg's great advice and go for it, best of luck

Ok not sure if its just me or if this is actually strange. I haven't changed any of the wiring since I posted last, or wired in the relay for the brown second accessory wire yet. But I figured out(PTL) that if I push the remote start button 4 times, it will start it and then 4 more times shut it off. I hadn't stated before the the primary remote does not work as in will not even light up or say anything on the lcd display of the remote. So I'm working totally off the secondary remote. Sorry if this doesn't make sense. It was written in a hurry. Thanks a bunch for your help! Aside from a few minor things yet, I should be good to go!

Change the activation number from 4 to 1 via the programming sheet.
Charge the primary then look up "paring" on either the owners manual or the programming sheet.
