obd 2 connection

Hello I'll be doing my second install on a 2011 Nissan sentra and the flashlogic bypass requires some connections on the obd port in the car I really don't want to cut or even tap at the obd2 connector so here's my question can I add a obd2 connector or extension and make all my connections there at the aftermarket obd2 connection and not the car actual harness that way if I wanted to remove it some day no work should be visible there.
I was thinking something like this.

i would just tap into the obd plug. its 2 wires and no cutting involved

Keep in mind any time you add a connector inline on a data wire that it is a potential failure point. I would say that yes you CAN make up a t-harness. I made one using some random OBDII t-harness I found on ebay for a Hyundai cruise control. It had all 16 pins present so I bought it and made a quick power point for my logic probe using pins 16 and 4 for power and ground.

Seems like a lot of extra work to us but if it is what you want to do, go for it.

A properly soldered connection behind the plug will be less frowned upon than a cobbled together adapter. May also void any kind of warranty from the remote start/bypass manufacturer. Just words to consider. Good luck either way!

I connect at the OBDII all the time...usually CAN hi and CAN lo...no harm in soldering into these wires, it is common practice and I have never had to make a cut at this connector.

Solder, tape, repeat!

Alright thanks everybody for all the input all try it the soldering method and get back to you guys how it went

I have another question does anybody has any experience with flashlogic flcan or any input I kind off want to start installing remote start and alarms on the side but I need an universal bypass for any customers I heard the Fortin evo is another option.

idatalink and fortin make great solutions. i use idata because my go to is compustar.the flashlogic is an idatalink. just rebranded for audivox

For the CAN wires on your Sentra: On many Nissans, you can find the blue and pink twisted-pair wires in the steering column harness. I usually just get them right there; it's easier than going to the OBDII.

Note that on many cars, there are CAN wires all over the car, but they're on different networks and don't "talk" to each other. So usually you have to get CAN where the installation guide tells you to. On Nissans, though, my experience has been that you can grab CAN almost anywhere you see it and it'll work.

About your bypass module choices and side work:

The FLCAN comes with a certain Chrysler firmware as default; you need the Weblink updater AND an account with them to change firmwares. And they only give accounts to verified professionals. If you're buying your products from a distributor, ask them to help you get an account.

The EVOALL comes with a default firmware that covers many, many vehicles, but far from all of them. So you're still going to want their Flashlink Updater. I'm pretty sure you don't need an account with Fortin to change firmwares; I'm not 100% sure.

So yeah, it does appear that the days of a pre-programmed, universal bypass are slowly ending.

I don't remember exactly.
There is a nissan software that you have to hook up locks at the bcm. Like 2010 titan if it has factory alarm. The can wires are there also.

Oh yeah Metz is right. If you have any plans to go to the BCM on this car for something else, the CAN wires are there too. Close to the corner of the plug where the locks are.
