I guess I totally misunderstood a long time ago on how that AlfaOBD thing connects and works on a 2018 and later pickup. As I said before, I was under the impression that in order to use that on my truck, Id have to pull the dash off around the radio, pull the 8.4 radio screen out of the dash, find that security module that’s behind it, unplug the connectors on both ends of it, and plug in that bypass....

Nope the bypass basically replaces the obd2 port. Then you plug in a obd2 reader into the obd2 port, connect through bluetooth make your changes and unplugged the reader. The bypass cable can be left alone or if you only plan on making a few changes at once and nothing more you can unplug the bypass.

This is what obd2 reader you'll want



If you have any detailed questions pm me and I can send some detailed pictures. They don't want the instructions or anything too detailed posted online so other companies can easily copy. Granted $50 for the bypass isn't expensive for a company to buy one and copy it

So one last public question- whether this bypass cable is taken out, or left in after programming, Chrysler’s computer will still be able to communicate with the truck regardless? In other words, the only way they’d “see” the cable is if they were to take a closer look at the obd-II port and actually see the foreign cable.

I would have to say, if you left the bypass in when you take it to the dealer, the only hassle you would get is, they would just unplug it so they can plug their dongle in. Then they would forget to plug the bypass back in and leave it dangling. They would honestly not give it a second thought, as long as they can get their tool plugged in and working.

To add: twice I’ve had my truck in for recalls and warranty work, and both times left the Bluetooth interface plugged in (the one pictured above). One time they set it in the cup holder, the other time the service writer handed it to me at the desk. Neither time was anything said about it.

I left mine in when I had a tpms sensor replaced under warranty. And they were able to get in and reset what ever they needed to. At that point I'd gone a couple of months without any sensors so I had the service tpms message so it had to be reset.
