Viper 4105V w/ Fortin INT-SL-PL 02 Trailblazer

Hey folks, I have been on this site (and all over the internet) for days trying to find what I'm looking for, and I either am just not seeing it, or it really isn't here. If it is here, my apologies. Please send me in the right direction. I did see a picture of an install of the Viper 4105V, but it had a different bypass module, and I'm lost.

I have an 02 Chevy Trailblazer (newer body style) that I'm trying to install the Viper 4105V along with the Fortin INT-SL-PL in. Does anyone know where I can find the wire to wire instructions? For example, I saw one post where it said I needed to access two of the wires on my OBD port, but no explanation of why, or what wires of what component to hook them to. (bypass module, or remote start) The wiring diagrams I found for both doesn't mention the OBD port either.

To be clear, I need the full diagram, not just the OBD wires. I'm not getting fancy with windows or anything. I just want the car to remote start and that's it. I didn't want to have to ask you guys for help, but I've exhausted every avenue I could find before posting this. (5 days in so far!)

Any help would be MUCH appreciated! Thank you in advance!

Fortin lists a can-sl-pl and an int-sl on their site. No int-sl-pl. Are you sure this is what you have?

Yes sir. I copied it straight from the box. It's a white sticker that says "INT-SL-PL". The sku is 7 70350 00228 2" if that helps.

Thanks for your help!

Here is the wiring with labeled Pictures in PDF.

2002 Trailblazer wiring with Labeled wire location Pictures

Take a look at the guide and see if it your module looks like this.
Int-sl:    https://fortin.ca/download/40441/int_chevrolettrailblazer_0207.pdf

beegbie,

I just downloaded that pdf, and it is not the same as I have. The box mine came in says "INT-SL-PL", but the installation guide it came with says "INT-SL+". It has a "vehicle fit guide" that says what features you can hook to it, and what cars it will work on. I purchased it on Amazon with my remote start.

I am not good with this site yet, as far as how to upload pics or anything. I see other people have done it, but I can't see how they do it. If you want to drop your email address to me, I'd be happy to send you a pic of it.

As far as the wiring goes, I'm getting ready to dig into it now. I'll post something when I get done and let you guys know how it turned out.

Thanks a million for the help you guys have given so far!! I very much appreciate you guys!!

The Model of Fortin you have is aINT-SL(Self Learning)-PL(PassLock)
And the firmware has been upgraded to the INT-SP+ which uses the same hardware loaded with different firmware. That combines the Transponder and passlock all into one firmware for more Brands of vehicles.

Fortin INT-SL-PL Guide REV. J (Most current from fortin)
If any Functions listed in this current Guide are not listed in the Original that came with yours. You would need to update the firmware to enable them.

lurch228,

Yes, that is what I have! If you wouldn't mind clarifying a couple of things for me, I would greatly appreciate it. I'm installing the units now.

1) For the "Power Unlock" and "Power Unlock" from the diagrams you gave, it says "use Directed interface module or see Tech Doc 1053". Does this mean to use a relay? I looked online, and even found an old post on this site, but when I clicked the links, it said the page couldn't be found.

2) What wires from the Fortin bypass am I using, and where do they go? I'm presuming I am doing the "Data Link" option on the instruction sheet?

Once again, I appreciate all the help!

1. That is for hardwire only! Only hardwire if data function is not working!

2. All solid wires for Data, if a data function doesn't then wire only that segmented wire for that function. Keyfob ICON is R/S and vehicle Icon to vehicle from Fortin bypass.

#. All heavy guage R/S wires to the vehicle, Split the Red's between the 2 12v of vehicle. Red to #1 12v and RED / White and RED / Black to #2 12v.

I doubt if a Fortin module from that era can communicate with a directed module through data so hardwiring is required.

It's one of 4 modules still listed on Fortin's Website for the 02 TrailBlazer.
So what do you mean by era?

They are still selling them As a available product to compare against the EVO-ONE,EVO-ALL, and the PASSLOCK-SL2-V2!

It's a module designed 15ish years ago. Long before Fortin supported d2d. If the op has a flash link updater and can change the protocol to d2d, and has a d2d cable, then it will work.

Are you able to confirm this is possible?

It's been a few years since I looked at the Fortin stuff.
With the current Fortin Flasher 3.31 and above they removed the D2D option. It's now only included in the firmware as a option of the EVO-ALL/ONE now.

@shawnchristy So the INT-SL+ will need to be hardwired to work with the Viper units.

They only did this to up sell the more expensive units if you want D2D communication.

We removed the D2D selction box you have seen in older version of the flash link because now you have to actually go into the EVO-ALL options menu and turn on the datalink protocol you would like: Fortin , AP/OFA or D2D.

First and foremost, update the Flash-Link Manager. If there is a drop down selection box in the EVO-All Firmware updates section to select Fortin or D2D/DBI then it is not the right Flash-Link Manager firmware. D2D is only now supported through the options menu with the latest firmware. You do not have to flash the EVO with a D2D firmware anymore, its only a matter of turning On the option. Latest Flash-Link Manager firmware is 3.31.
