viper 4704 on 2012 nissan titan

I can send the xcel file to you if that would be better?

I copied it to Word and it is readable. First, I am not a DB-ALL user, so I don't know how "feature programmable" they are with the XKLoader2 cable attached ( like the Fortin or iDatalink modules where you can turn off certain items and functions). The reason being, you are mixing the wiring and functions between the D2D harness supported functions and going W2W on others.   ( I am assuming D2D because you did not manually connect the Vipers Dark Blue (-) Status Output wire to the DB-ALL (-) GWR Status Input and the DB-ALL Pink Ignition wire is not listed as connected to the Vipers' thick Pink IGN1 wire.) Examples : The DB-ALL supplies a Brake input via D2D but you are also manually running a wire from the Viper to the Titan's physical Brake pedal wire. The DB-ALL supplies a Tach signal via D2D and you are using that. The DB-ALL does the door lock thru D2D and you are also directly connecting the Viper to the key cylinder wires in the drivers door. The Viper sends a Parking Light control signal to the DB-ALL via the D2D harness so the DB-ALL can control the Parking Lights but you are also hardwiring a Parking Light connection from the Viper to the Titan. Anyway, it's confusing to me. I have never tried it that way. I am not sure how the DB-ALL and the Titan will react to that set-up. For me, I would connect the two units in the W2W mode and use the DB-ALL for all it's worth ( Tach, Brake, Parking Lights, Hood Status ( if Factory supported ), etc ). The only point of concern is the Factory Alarm. Perhaps a call to XpressKit Tech Support can clear that area up before install. Going W2W, you could just wire up the Vipers lock wires to the BCM or inside the door and bypass the DB-ALL for that issue. Additionally, try to find a sealed relay for the IPDM. While it is not directly exposed to water splashes, it is more subject to the elements in the box under the hood.Soldering is fun!

Sorry if I'm confusing you. I do not intend to mix the 2 types of signals and am probably over thinking this to the point I'm crossing signals. Hence my questions. I'm trying to eliminate what would be D2D and what would be W2W and I believe I was mixing up the connections I need to make. With D2D all of the functions found in the W2W are there. The DB-ALL seems similar to the units you are referring to where the functions are programmable. I can turn my OEM alarm on and off with the xpressloader2 and I can program which features I want to use. Glad to know I do not have to get inside my doors if I don't want to. I will give them a call to make sure I'm covered. I'll eliminate the 3 connections you are referring to and I only have to make the connections for: neutral to ground, rear defogger, hood pin, (possible blue for horn since I'm using a 2-way that can arm/disarm alarm) and the Accessory output to the relay. I'll contact xpress to clear the rest up. The relays I purchased are sealed automotive relays. I do really appreciate your patience and responding to my questions. Many people would just tell me to take it to someone and have them do it.

I've been meaning to ask you what this relay does in the circuit? Obtain 30/40 Amp SPDT relay for ACC2. Wire as follows : Relay Pin 85 to Viper H2/22 Orange (-)200mA Accessory Output Relay Pins 86 and 87 to Green +12V constant @ Ignition switch harness through 20 Amp fuse Relay Pin 30 to Purple ACC2 @ Ignition switch harness Relay Pin 87a    not used I understand that when the 200mA signal is sent from the Viper the coil is energized and the relay switches state sending 12V to the ACC2 wire. What does that actually do?

The external relay is used to supply power to the Titan's Accessory2 circuit. The Viper can only handle 4 of the 5 ignition circuits ( IGN1, ACC1, Starter1 and Starter2 ) but the Viper conveniently provides these (-) 200mA outputs to control relays for any additional vehicle needs. Each of these circuits ( like Starter1 & Starter2, ACC1 & ACC2 ) is isolated and should be handled the same way during a remote start. An installer should never connect the thick Yellow Starter Output wire to two vehicle starter wires. I do not know exactly which vehicle circuits are controlled by the ACC2 wire. It could be completely un-necessary things like power mirrors, heated seats, wipers and the radio.   In some vehicles, not powering an ignition circuit will cause CEL's and in some cases transmission damage. If you can go into the DB-ALL programming and turn off the Door Lock control and E-Brake Status Output, you could connect the Viper to the DB-ALL via D2D. The D2D harness would provide the Viper with the Tach signal, the Brake signal and possibly the Hood Pin Status along with taking care of the transponder bypass. At the Viper, you would connect it's lock outputs to the BCM ( as shown in the iDatalink guide ) and the Neutral Safety to chassis ground. At this point most of your wiring chart is good, just delete the H1/5 and H2/16 connections as they are handled by the DB-ALL via D2D.Soldering is fun!

I saw an install online with the connection you've said shouldn't be done. Here are the DB-ALL functions. The locks and brake are covered as well as the hood pin if I have one. DL-Lock DL-Unlock DL-Trunk RS-Request engine coolant temp. RS-Request intake air temperature (outside temp) RS-Request RPM RS-Ground when running RS-Start command RS-Stop from remote RS-Starter RS-Ignition command RS-Ignition from RS RS-Aux1 RS-Aux2 ST-Hand brake ST-Hood ST-Trunk ST-Driver door ST-Other doors ST-Brake ST-Ignition OEM Keyless-disarm OEM Keyless-arm SS-Alert Status SS-OEM Alarm RS-Request Runtime Looks like it's all about covered. Thank you again.

I finally got around to installing the Viper. Install isn't that bad as long as you take your time and pay attention that everything is wired and set properly. A big thank you to Kreg. Some other observations. With D2D the door lock wires are not required and the Brake Pedal shutdown is not required. And, if you are going to do this yourself or even ever want to change anything buy yourself the programmer for the Viper and for the DBALL.    However there are 2 issues I'm still dealing with: The parking lights do not flash during lock or unlock press even though I have the polarity set to + on the Viper. On the DBALL I've tried all 3 settings for light flash and still nothing. Do I also need to set the lights in the Viper? The rear defogger: I thought I should use wire H2/3 but it looks like maybe I should use F2/9?

For the rear defroster, use H2/3. With the BitWriter you can program it to Defrost and select the correct "Pulse" or "Latched" setting.   Menu 3, Item 11 If you tried everything with the 4704V and DB-ALL settings, why not just go W2W with the Parking Lights. Set the Vipers' Jumper/Fuse to (+) and make a direct connection from H1/5 White wire to : Parking Lights (+)     RED / Blue (+)        @ electric brake pre-wiring left of steering column, White 6 pin plug, Pin 4 Also verify that Menu 3, Item 12 is set to Option 1.Soldering is fun!

kreg, thank you again. The manual states that Menu 3 Item 11 is from H2/9? I'll switch and see.rd wire it Ok, I'll check Menu 3 Item 12 1st and if need be go W2W as you directed. You're instructions have really helped me. I don't know how you guys can lay backwards under dashboards all day long.

The W2W was required for the parking lights. So, that part is done. I just set the Viper so that the lights are on when the vehicle is running. And now the lights flash during lock and unlock. For the rear defroster I measured the signal on the yellow/black wire and the 12 volts is constant so "latched" with a button push. I set the Viper to latched and I need to measure the voltage when the remote start is running to see if there is 12V on the wire since the yellow light for the button does not light up. I really appreciate all of your help. You made a tough install much easier. Trying to program the remote is a bigger pain than the wiring I think.
