engine trouble need help!
Ok il look in the manual and see if I can find anything. I also noticed when I put the SCT tuner on the truck the fuel pump runs constantly and I have to remove the relay for the fuel system to avoid building up too much pressure once the tune is on and I unplug the tuner it is fine not sure if that has anything to do with my problem just throwing it out there
Mine does not run constantly with the SCT tuner.
You might have something else going on, like fuel leak, stuck open injector, broken fuel regulator, etc.
That can also cause issues. Fuel pressure should be 49 psi +/- 5 psi max.

I could not get that like to work on my phone I'll have to try it on my PC at home...I think I will also try to test the injectors and see if all is good there. It only takes a few mins and it certainly can't hurt
It's the communications port that you plug your scan tool into to chat with the computer..... I have never tried to find mine.... I always thought it was up under the dash, above the drivers knees.... No huh?
You need a scan tool that can read data, and display it in (sorta) real time. I don't know if the fellers at the parts store will do that trick or not. If you have a laptop, you can get a cable for under 50 bucks, and software for free..... to take the place of the scan tool. You won't be able to change anything, (without spending some bucks....) but, you WILL be able to see ALL SORTS of data. Makes troubleshooting performance problems MUCH easier.

Page 7-14 of the manual states:
The DRB connects to the data link connector (Fig. 31) located at the
lower edge of instrument panel near the steering column.Dave
I have located a 6 pin connecter on the passenger side of the truck about 1 inch down off the main harness near the plumbing for the a/c it comes right off the main harness tho could this be the port I am looking for...it has 3 rows of 2 pins and the first 2 sets of pins are horizontal and below that there Is another set of 2 pins that are vertical
Ok, here's where it gets interesting.... went and looked at my truck. There is indeed an OBDII port above the drivers knees, under the dash...... I also have the same six pin connector that you found. At this point, I don't know if Dodge used that connector under the hood for the DRB, or what..... I am also unsure if you can get the data you want from the OBDII port under the dash..... Got any friends that work in a shop, that have a good scan tool??
