You have chosen a slightly advanced install for your first time. The Manual Transmission will add a bunch of
things to the install.
First for the questions.
1. I can't find anything on its harness descriptions that fit a "starter 2 output". Where do I connect this to on the 5706v alarm module?
You will need another 30/40 Amp SPDT relay for this vehicle wire. You will use the Vipers (-) 200mA Starter Output. This wire can be
found at Pin 21 VIOLET/YELLOW (-) 200mA STARTER OUTPUT. Relay wiring below :
Relay Pin 85 to Viper VIOLET/YELLOW (-) 200mA STARTER OUTPUT
Relay Pin 86 and 87 to +12V through 20 Amp fuse
Relay Pin 30 to FR-S RED/WHITE (+) @ IGNITION SWITCH HARNESS, WHITE 8-PIN PLUG, PIN 1
2. D2D Mode and necessary Viper wires.
First, make sure you flash the ADS AL-CA with the DBI-AL(DL)-SUB3. DBI flavor of firmware is required for Viper D2D communications.
Second, look at the iDatalink install guide ##47724 and the chart on Page 2 of 19 for details of what the ADS AL-CA does for you. If it is listed,
it comes via the D2D connection.
3. A connection from a relay I'll install at the clutch switch, going to negative starter output on the viper, which I assume grounds out the clutch
switch during remote start to convince the car to start.
Not exactly. The car needs to see the clutch depressed to start the engine. The R/S system fakes out the car by applying a (+) 12v to the
specified wire. The relay is needed to convert the Vipers (-) Starter Output to the (+) the car needs.
4. How is D2D mode enabled? Is it just a thing that happens when the system realizes it's connected to modules that support it, or do I have to
enable it somehow?
For the Viper, it is automatic. For the ADS AL-CA, you must set the Installation Mode to Data ( one blink ) and lock it in after flashing and
before vehicle programming.
5. The one +12v wire on my ignition switch seems to power the ignition relay I'll be installing, the viper itself, and the bypass through D2D port,
so I don't need separate 12v power to anything from another circuit. I assume I can take the clutch relay and connect the two pins requiring
12v power (according to ads diagrams) and splice them in that ignition 12v power wire too? I'll of course be checking all that with my voltmeter.
There will be a total of 6 R/S wires that need to connect to +12V constant. The Viper doesn't draw too much power for itself but it does power
the siren. The ADS AL-CA uses very little power. The Parking Lights are data so you might get away with the lone ignition switch harness wire.
Of course, the safe bet is to go right to the battery with a proper gauged and fused wire.
6. The bypass was flashed for my car when I bought it, so I get that I need to do the key clone thing, and have the requisite iOS cable for it.
See number 2 above.
7. Are there any other connections needed in D2D mode? Things like the horn and trunk and such (defogger?) all taken care of via the Can interface?
The horn might not be necessary if you are installing an alarm system that has a siren. Trunk is handled by Data. Defogger is seperate, if you want it.
A few extra notes for this M/T install.
1. The Viper must be set to Tach Mode. The ADS AL-CA provides a Tach signal via D2D. You will probably have to do the Viper Tach Learn process.
2. The Viper gets it Neutral Safety wire input via D2D as the vehicles E-Brake signal. The E-Brake must be on to R/S after a successful entry into
Reservation Mode.
3. You should solder all your connections to ensure a solid, reliable install.
Soldering is fun!
