Im having trouble locating the BCM for my car, If you read this link apparently some cars have different BCMS. Reference Post 1 (this is the CORRECT BCM), and if you reference post number 15(that is how my bcm looks, and all the wire colors are either incorrect or missing according to the latest directechs. I am having trouble finding the door trigger / and the trunk hatch pin. Please can some one help me i have those two wires left and i would like to close up the underneath of my dash.
Thanks in advance

The BCM shown in #15 is a common BCM style used in most Nissans a few years ago. If you reference an 06 Armada, Pathfinder, Titan, Frontier, Maxima, Altima you will see they too have the same style BCM with the same plugs. You should be able to get info from these cars to find what you need. Wire colors may be different but pin positions are the same. If wires are missing this doesn't mean you can't get what you want there, add a wire into the pin. For instance, we do this on the Maxima for lock wires without going to the door for them. We sinply use the same pin slot as the Frontier. DEI lists pin positions, hopefully you can find info from there....

The BCM will click when you operate the power door locks. Just hit the locks and listen.
It's in the driver's kick panel, next to where your left foot would be if you were sitting in the car.
The BCM also has the fuse box as part of it.....if you can find the fuses inside the car, you've already found the BCM.

Thank you guys for all the great help, and ideas I am still having trouble finding the correct wiring for my BCM. The BCM I have has a 40 pin connector, and all of the information for the driver door trigger is in pin 62. Hopefully you guys can keep up the good work and get me outta this bind
Thanks

Ok, so heres an update. I found my driver side door trigger in the harness that goes from the drivers kick to the rear of the car, however i unscrewed the door trigger button, and the color of the wire is GREEN/ Black. That is when i found it in the harness going to the rear. It does NOT go to the 40 pin BCM connector that i have. anyone have any ideas about the trunk pin, and the passenger side door ? I cannot find any wiring info about this 40 pin connector for my BCM. Also i shouldnt really say im having trouble locating the BCM, i am having trouble locating the correct wires at the Pins seeing that i have a different generic BCM for my car.

Nissan counts all 3 plugs as one set of pins, so pin 62 could be in a smaller plug. I think the plug with the larger gauge wires is the first plug, then when you count all these the next plug starts it's count from there not over again. What i do is start my pin count from one i already know is correct and count from there. You need to look at ALL 3 plugs knowmatter how many wires are in it... ------------- Mike M2

The door triggers aren't in the 40-pin plug.
The 40-pin plug has the defroster wire, and the empty pins where you can add wires for the doorlocks.
There are two or three other plugs, with maybe 5-10 wires in each.
All of the individual door trigger wires are together in one of those other plugs.

I will check out the other connectors when I get home, I have 3 plugs the 40 pin connector and. 2 others.

hey dcman14, any luck with this? I know it's over 9 months ago, but I'm in the same situation right now. I hope you're still getting notifications for this thread. Thanks!

Here is the info for the '06 coupe BCM: https://www.nicoclub.com/FSM/G35/Coupe/2006_G35_Coupe/bcs.pdf (it starts on page 11) Here is a layout of pin numbers for the BCM: https://www.nicoclub.com/FSM/G35/Coupe/2006_G35_Coupe/pg.pdf (page 71) Some of Nissans service manuals are funny in that they don't give wire colors for the BCM - to find actual wire colors you need to dig a bit deeper in to the other subsections of the manual for specific BCM functions. If you have a specific question about a specific wire I can look it up and provide the info. ------------- Kevin Pierson

are there any options inside the cabin for the hood pin and tach sense? Are these two even required to get the RS to work?

It looks like on the '06 the hood pin signal goes to the IPDM (fuse box thing behind the battery). You can pick up the tach at the ECU under the passenger dash - grab anyone of the 6 injector outputs (look at the EC.pdf file in the service manual above around page 105 or so for the ECU wiring info).

I've never found hoodpin inside on those cars.
I did manage to find tach under the passenger dash on ONE of these cars, which was GREEN / WHITE, but I never could find it again.
If you're using a transponder bypass module such as something from ADS or Fortin.
Your two questions about whether these things are necessary for operation.......if you use the search feature you can find lots of debate and disagreement.
But, to give you a direct and short answer:
Hoodpin: Remote start will work without hoodpin. However, it's a safety feature. The remote start would work all the time, even if the hood is open, even if someone has their hands on the drive belts.
Tach: Depending on how good the voltage-sense mode is on your remote starter, it'll work, yes. Most installers agree that tach sensing is better. Some think it's an absolute neccessity, and others hardly ever use it at all and have good results.

Thanks for the feedback! Is the tach for the "anti-grind" feature? As long as there's a tach "on" signal going to the RS, it knows not to let another "start" signal try to trigger it? I want to make sure I understand that. What is the RS looking for as far as the tach signal goes? Would any "on/positive" signal work? Say the Accessory? The accessory signal is powered when the car is on, right? Or is that not how it works? As for the hood pin, I can switch off the "Neutral Safety" switch when dropping the car off for service, yes? But I guess you're right, it is safer with the hood pin signal connected. I've got to run the siren wire thru the firewall anyway, might as well bring the hoodpin wire along with it. Anything else that needs to go into the engine bay? Thanks, again!

Duh, no, that won't work. The accessory comes on even before the engine cranks. Nevermind that part.

The anti grind feature works by energizing the ground when armed wire while the vehicle is remote started. This will effectively activate the starter kill and prevent the key from cranking the car WHILE the remote start is active. A tach signal is typically a digital on/off signal with a frequency related to engine speed (ie a fuel injector pulses every other motor revolution). Basically, with this signal, the remote start can calculate how fast the motor is spinning. I would hook the hood pin up. Like you said, just run the wire with the siren wire. ------------- Kevin Pierson
