wiring remote start + dei alarm 8th civic

Hello Forum members! I am installing a Viper 5204V alarm which is an alarm + remote starter. I have a 2009 Honda Civic EX 4 Door 1.8 L Automatic. I have experience installing an alarm, but this one is a little advanced for me. The former alarms that i've installed was on older model civics, which also did not have remote stert to make it more wires and more difficult. For this install i am bringing in an Xpresskit DB-ALL2 unit to integrate with the factory system. I am planning on doing a D2D (Data to Data) connection to hopefully avoid a lot of wires. I have copy pasted the wiring description below of all the wires that the 5204V has, and left commens next to many things i have a question about. Upon successfull completion of this installation, it is my goal to try to make a DIY for the 8th gen civic so someone else can do it quicker :) Harness H1 is not too bad but there are a few things im not sure about Harness H2, i feel like the bulk of it is provided by DBALL or is just not needed, I need verification and maybe narrow down what I actually need. It also needs Ignition, but thats being asked in H3? Harness H3 (the scariest) this one is really what scares me the most. I have cut the starter before on another car and installed a Kill relay and it was fine. Does this one have an integrated one into the brain? Also some of the wires im not really sure what to do with. I would also love to get the defroster (front and rear, or at least rear) to get to work with remote start. Not sure if its okay to do this even during the summer? Any assistance will be greatly appreciated :) H1 Harness H1/1 RED (+)12VDC CONSTANT INPUT - @ IGNITION SWITCH (BROWN, 7-Pin Plug) Pin 3 H1/2 BLACK (-) CHASSIS GROUND - Any Ground H1/3 BROWN (+) SIREN OUTPUT - Output to Viper Siren H1/4 WHITE/ BROWN PARKING LIGHT ISOLATION WIRE - PIN 87a of onboard relay    - Not Used?

Thank you very much for your reply. Now its just the H2 Harness that i need to figure what to use and what not. (I think most is provided via the DBALL though) Also i see that on the H3 there is a note for "***Program to ACC2" what does that mean? Much appreciated Thank you very much again!

The H3/7 Pink/White wire is known as the Flex Relay and has a selectable output.  The Factory Default is Ignition2 but

for your Civic you want it set to Accessory2.  You will need to program Menu 3, Item 8 to Option 2.

Here is a link to the Viper 5204 Install Guide :  https://www.the12volt.com/installbay/file.asp?ID=1150

Haven't had a chance to look at the H2 wires yet, but will try latter.

Verify that the DB-ALL2 is flashed with the 402.HONDA4 v3.06 firmware.

*        Domelight Supervision might not be required.  Check to see if dome lights come on with a Viper Unlock Command

**      After install test to ensure that opening the hood during a remote start will shutdown the engine.  If this does not         happen, install the Viper kit supplied Hood Pin Switch and connect to Viper H2/17.***     It is possible that the Viper 5204 won't handle the DB-ALL2's Tach Output via D2D.  If the Viper won't Tach Learn,         hardwire this signal between the DB-ALL2 and the Viper & obtain a successful Tach Learn.

I think everything is pretty clear here then. I do want to ask you a question about that Tachometer input though. First of all what is it used for? and second where do i get the input for that wire? I've read from sources on the internet that you have to get a feed from the injectors. Wasn't really sure how to get to this? Again, really appreciate your time and help! As an aside, the DB-ALL does save quite a bit of that wiring mess !:)

Your Civic does not have "one touch starting" or built-in Anti-Grind.  One touch starting is where you can quickly turn

the key to Start and release it back to Run.  The car's computer will continue to crank the engine until it starts.  Oncerunning, if you turned the key to Start again, it will grind the starter motor ( no Anti-Grind ).

The Tach Input is used by the R/S to control the H3/4 Starter Output length.  Your Civic's actual crank time can vary by

a bit depending on the engine and ambient temperature.  If you used a fixed length crank time, it might over crank thestarter motor in the summer when the engine was warm and not crank long enough to start the engine on a cold winter morning after the car sat over-night.  The R/S learns the engine's RPM when starting up and uses that value to crank the engine up to starting speed at any temp.  The additional benefit when running in Tach Mode is a Viper feature that will shut down the R/S system if an over-rev situation occurs during R/S run time.

The Vipers Starter Kill / Anti-Grind feature is nice because it will prevent an inadvertent starter grind by turning the key

too far ( Start position ) during key take-over.

There are several places to get the Tach signal.  The first place should be from the DB-ALL2 via the D2D connection.

If that doesn't work properly, you can hard wire the DB-ALL2's Tach output to the Vipers Tach Input as follows :DB-ALL2 Red 12 Pin plug, Violet/White wire @ Pin 5 to Viper H2/23 VIOLET/WHITE TACHOMETER INPUT If that doesn't work properly, then try going from Viper H2/23 VIOLET/WHITE TACHOMETER INPUT to the unique ornon-common color wire at any F.I. or Spark Coil.

As an interesting fact i found out that the 8th civic has a Tach wire as part of the wiring harness going to the factory Radio. Its used for the factory radio to control the volume with Increase/Decrease in speed. How would i know if the DBALL is infact giving the viper a valid tach reading?

I did an 08 Civic last week, 5704 with a DB-ALL2 and SmartStart. D2D, 1 wire required, H2 BLACK/ white to parking brake or ground if auto. Being European, white at H1 to green at Hazard switch, set POS output. Physically there's a remarkable lack of space under the dash so I removed the instrument panel. 4 Philips screws and some tugging. Once out there's a load of space behind the gauge cluster to loose the unit. Tip, don't turn on ignition or run engine with that cluster disconnected. Yes DB-ALL2 does provide tach. You'll know as soon as you go to programme tach. Ignition switch completely different colours, 1 x 12V+ input, 2 x ignition, 1 x ACC and this model has a separate push starter, just like the S2000. Lock/unlock also different colours. Ignore dome supervision, already on vehicle. On the Euro cars DB-ALL2 also controls factory alarm and the factory key also controls the Viper.
