2009 Nissan Xterra, Viper 4806V Remote Start

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.

Thank you! What if there ARE wires in the Arm and Disarm locations? If there are no wires, then I basically shove the diode into the socket like a pin?

Yes, that is what the diodes are for, they fit pretty well into the socket for a decent electrical connection. Just secure them with a tie wrap to an adjacent wire as they can be easily pulled out. I usually tin the diode legs with some solder to provide a little extra thickness and grip. If there are wires in those locations, you can still use the diodes - they won't hurt anything.Soldering is fun!

I'm trying to figure out which of these wires I need to be connecting. Here's what the DB3 bypass diagram shows should be connected. And here's the Viper wire connections list. I've added in red what I think some of them are supposed to be, but looks like I'm still missing ACC2 and Starter2. Now it does look like the Red/Black wire (12VDC Constant input for ACC and starter relays) is what I would connect to 86 and 87 on the relay, yes? Or is that incorrect because it says it's input, and I need to connect 86 and 87 to 12V output?

Good news today is I confirmed the trans neutral safety switch is (-) when in gear! Neutral 2nd So the only thing left I still need to figure out is the ACC2 and Starter2.

Here are the connections for the 8 Pin ignition harness. It covers everything except the ACC2 wire.

Thanks Kreg!

Do I need to program the Viper with software? Or is this something I can program after install like you do when programing functions for the remote? Didn't get as far as I wanted today but that's mostly cause I didn't know what to do with the 8 pin ignition harness. So I just sat around and organized tools. By the time I saw your answer it was a little too late to get back into it. But I made progress on the harnesses and the relay! Cathode side connects to 86, correct? I hope so :P Also, I can't believe I've never owned a butane soldering iron until now. Makes soldering under a dash SO much easier when you don't have to worry about a cord.

Yes, the Flex Relay output ( Pink/White ) can be selected via Viper programming using the supplied remotes. See Menu 3, Feature 8, Option 3 for Starter2 output. There should be programming instructions in the 2 page Install Guide. It take a little practice to get used to using the remotes to make programming changes. Yes, again, the diode Cathode ( stripe ) goes to Relay Pin 86 if you follow the above diagram and make Pin 86 the (+) side of the relay coil. Nice work on the relay socket wiring - very clean. Looking at the 4806V Install Guide, the thin Orange (-) Accessory Output that goes to Relay Pin 85 is Pin 23 on the Aux/Shutdown 24 Pin harness. I'm sure you found that but just to clarify my earlier post. No cord on the soldering iron makes things easier. I couldn't find a butane iron that gave me the temp control I wanted so I'm still using a Hakko FX-601 soldering iron.Soldering is fun!

I guess that's better than having to get the module programmed by a shop or distributor! I'll take a learning curve over that :P And I do appreciate the clarification on the Acc. output. Another question: the Parking Light Output on the remote start says it's only necessary if parking lights aren't supported in data. How can I find out if they're supported by data without installing everything first and trying it? I kept that wire long with the expectation that I would connect. But I can always trim it short if my lights are supported by data.

Look at the DB3 Install Guide. There should be a list of supported D2D featured.   While I don't have a copy with me, From the wiring diagram you posted, it appears that Parking Lights are not supported via Data. The wiring diagram shows a (+) Parking Light output from the R/S controller that is directly connected to the vehicle. The exact vehicle wire should be listed in the DB3 Install Guide in the Harness connections section.Soldering is fun!

Excellent! Found the parking lights in the kick panel and got those connected. Can you explain the clutch wiring to me? The DB3 instructions say to wire the clutch output to either 1 of the 2 clutch wires. However, the Viper RS came with pictures of all the wire locations and in this picture it says to short both of the wires with a relay?
