Greetings!
I was hoping to get some answers before I start this install.
I have a 2009 Xterra with M/T. Vehicle has a chip key.
I purchased a Viper 4806V remote start system and a Directed DB3 bypass module based on recommendations from the Xterra forums. However, actual install walk-throughs don't seem to exist. I know I'm capable of doing the install myself, but I would still like some form of walk-through or some diagrams if possible.
1. Will I need to use any other wires than what is listed here?
   There are a lot more wires in the Viper harness than what is in the thread I linked. I assume those are just not used for the install?
2. Will the DB3 module allow the car to remote start even without the key present? I assume this is the purpose of the "bypass" module. Or will I still need to sacrifice a key to keep inside the car near the ignition for the remote start to work?
3. My research says that my transmission has a neutral safety wire coming off it which is what the computer uses to tell the transfer case that the transmission is in neutral for 4WD. Can I use this wire to install the remote start like you would in an automatic transmission so that I don't have to go through the manual transmission "shut down" procedure each time?

"1. Will I need to use any other wires than what is listed here?" It depends... Does the vehicle have the factory alarm system? Was the DB3 flashed with the 403.NISS1HT v4.20 firmware for your vehicle? The DB3 w/403.NISS1HT Install Guide has a more complete list of required connections. Hopefully the supplier of the DB3 flashed it correctly and supplied you with the 21 page Install Guide. The install guide does have diagrams of the vehicle connectors, etc. If yes, then the DB3 will supply the Tach, Brake, E-Brake, Hood. Trunk and Door pin signals. It will also handle the Transponder bypass, Locks, Parking Lights and Hatch release.
"2. Will the DB3 module allow the car to remote start even without the key present?" Yes, after the DB3 is successfully programmed to the vehicle it will bypass the vehicles transponder immobilizer system during remote start-up without any key in the vehicle.
"3. My research says that my transmission has a neutral safety wire coming off it which is what the computer uses to tell the transfer case that the transmission is in neutral for 4WD. Can I use this wire to install the remote start like you would in an automatic transmission so that I don't have to go through the manual transmission "shut down" procedure each time?" Possibly. This is a major safety issue. You must locate this wire and verify that it does indeed indicate that the manual transmission is in neutral and that it only outputs this signal when the transmission is in neutral and at no other times. If this "neutral signal" is a (-) type output, then you could connect it to the Vipers BLACK/WHITE (-) NEUTRAL SAFETY /PARKING BRAKE INPUT wire.
What you are missing...
Clutch bypass - the DB3 has an output for this and the vehicle wire is indicated in the the DB3 install guide.
Accessory 2 power - the Viper 4806 can only supply 4 ignition type outputs ( ING1, Starter1, Starter2 and  ACC1. If the ACC2 is required you will need a relay. The DB3 install diagram shows  it connected.
Two 1N4001 diodes for the Arm and Disarm wiring.
An in-line fuse holder w/fuse for the ACC2 external relay.
As far as a step by step guide, well...
1. Obtain any extra items ( diodes and relay ) plus Tesa tape, Scotch Super 33+ Electric tape, etc.
2. Make up a wire connection list for all necessary connections. If you post it, the 12V Forum members can review it and make recommendations.
3. Bench Prep the system / modules. Cut unused wires to 3 inches and bundle/insulate. Bundle wires with Tesa Tape in groups by intended end location.
4. Disassemble vehicle and locate/test all needed wires.
5. Remove Viper fuses*, position Viper, run wires and cut to length. Solder all connections. Insulate all connections with electric tape.
6. Run antenna harness to windshield and install antenna.
7. Install fuses.
8. Program DB3 to vehicle successfully.
9. Make any necessary changes to the Viper Programming Option Tables.
10. Do a Viper Tach Learn.
11. Test the Vipers lock and unlock control. Test the Hatch Release.
12. Test the Viper R/S function.
13. Test the Brake shutdown.
14. Test the Hood Pin shutdown.
* I install while hot. I do not unplug vehicle connectors other than N.A.T.S. and main ignition switch connector, if needed.
Soldering is fun!

"It depends... Does the vehicle have the factory alarm system?"
Yes, the vehicle does have the factory alarm system. Well, it's the immobilizer but yeah when the car is locked the little key symbol on the gauge cluster flashes.
Looks like it was flashed with 403.NISS1HT 4.18, not 4.20. But yes, it came with a Directed 21 page install guide.
Now that I look through it more thoroughly, I do see this page. I guess I only confirmed that I got the guide when I bought the DB3 but never actually looked through it.

This is a major safety issue.
I'm definitely aware of the safety concern with a manual transmission and I'll make sure that if I can't 100% verify that it will be in neutral then I will install it the normal way and use the reservation mode for manual transmissions. I'd just like to be able to do it the other way if possible and read about that neutral wire and got excited.
Clutch bypass
I see that in the diagram. "Clutch Output"?
Accessory 2 power
Looking at that diagram, it looks like more than 4 IGN outputs are needed. Ignition Output, Acc 1 Output, Acc 2 Output, Start 1 Output, and Start 2 Output. I believe I saw a post on these forums or possibly on Youtube about how to set up the relay that's needed. But if you have notes for me that would also be helpful.
Two 1N4001
As in this guy?
An in-line fuse holder w/fuse for the ACC2 external relay.
I actually installed 12V constant and 12V ignition fuse blocks under my front seat for purposes just like this!

Also, I very much appreciate your response! Thank you.

The best way to test for a Factory Alarm system is to turn the engine off, stay seated but open the drivers door and press the inner power lock button, then close the door. Wait about 2 minutes and then open the drivers door using the inside handle. If the horn starts beeping, you have the Factory Alarm system. Having a chipped key is just a passive anti-theft device and the blinking light on the dash can sometimes be found on cars without a Factory Alarm.
Having an older version of firmware isn't usually a problem. Most of the time they do firmware updates is to support new vehicles and not to correct issues on older vehicles. With your 2009 Xterra I'm pretty sure it's been stable for a while. Just use the Install Guide that matches your firmware.
Yes, those are the diodes you need for the Arm and Disarm connections at the BCM. You could get 1N4007 diodes and use one for "coil quenching" on the external ACC2 relay, too. The 1N4007 will work for all your needs.
For the ACC2 relay, get a Bosch style 30/40 Amp SPDT relay with 5 pin harness and wire it like this :
Relay Pin 85 to Viper thin wire (-) Accessory Output
Relay Pin 86 and 87 to +12V constant fused at 20 Amps
Relay Pin 30 to vehicle Accessory2 wire at main ignition switch harness
Relay Pin 87A not used - insulate
That's a nice setup for power under the front seat! 2009 Nissan Xterra, Viper 4806V Remote Start -- posted image.   Excellent idea and well executed.

Okay maybe I don't have the factory alarm cause I did that and no honking horn.
So just to confirm, I can use the 1N4007 in plae of the 4001?
We've had a hell of a blizzard in Denver so I haven't had time to check that neutral wire but I'll hopefully get started on the harnesses soon.

Yes the 1N4001 and 1N4007 can be used for both purposes. The only difference is the higher voltage capability of the 1N4007.
Here is an excerpt from Electrosome :
Peak Repetitive Reverse Voltage of 1N4001 is 50V while that of 1N4007 is 1000V. RMS Reverse Voltage of 1N4001 is 35V while that of 1N4007 is 700V.
   Typical Junction Capacitance of 1N4001 is 15pF while that of 1N4007 is 8pF.

Great, thanks! Looks like I already have a free 40/60amp relay mounted with lead wires so I'll just use that. Guess all I need to get started is the diode and some extra wire since all I have is spools of 14awg.

Okay so based on the DB3 install instructions, can I effectively ignore any of the connections that are not bolded? I assume my vehicle is going to be using the D2D connections and not the W2W ones. Obviously I can ignore the "no connection" ones. But I'm not sure why some of them are bolded and others are not.

In the wiring diagram, which direction should my diode be facing? Should the cathode be towards the vehicle or toward the remote start?

From the previous April 11th question, I would follow the diagram. The actual pin by pin info chart provided is very complete to cover all possible install types.
Diode use : If there are no wires in the indicated ARM and Disarm locations at the BCM connector, use the diodes and have the band towards the Viper 4806V controller. Try to Zip tie the diodes/Viper wires to an adjacent BCM wire to provide a secure and stable connection.
Soldering is fun!
