You can either install a boost capable MAP sensor in place of whatever MAP sensor you have now and then dash logic can read data from it the same as it reads all the other engine parameters/PID's
Or you can install an additional boost capable MAP sensor and wire it directly to the Dash Logic external inputs

Ask whoever built/tuned the car. It's much easier to tune them with a boost capable MAP sensor, so I would be surprised if it doesn't have one already, but it's possible I suppose. You haven't given much info on your setup.
If you don't have the proper one, get something like the ZR1 sensor. Two values will have to be changed in the tune for it to work. Hopefully you have someone nearby that is fair and won't charge you for such a small change (assuming you don't have HP Tuners)

No problem, it's easy to spend other peoples money 
Glad you like it though. I've had three widebands now and the plx gen4 is by far the best. It's dead nuts the same readings all the time and I haven't had any errors, it reacts fast, etc. Good sensor IMO.

Every car has a MAP sensor. The question is whether it's the stock one or one that can read boost.

If you already have one, you won't need to do anything. Just read map info with Dashlogic and it will show boost. If you have to add a second map sensor. That's when you have to add a wire to the Dashlogic.

If your current MAP sensor will read boost, then just plug dash logic into the OBD port and boost #'s will show up on the DIC. No wiring required.
MAP sensor will send a signal to the ECM, ECM will convert it to psi, then dash logic will read the value from the ECM. No new wires needed.

Ok, I found out I do not have a boost sensing map......So can I just plug a new one in and it will read automatically or will the car have to be tuned for it? If so I need another option for now as I don't want to get the car tuned for this YET, that's later......I just need to see what kind of boost I'm running before I make the changes I have in the works

Without seeing your tune I can't be 100% sure whether more will need to be done or not though. Do you know if it's running MAF, SD or mixed mode?
You can always just run a separate MAP sensor that is wired directly to the dash logic interface instead. A ZR1 sensor will work fine for that. It needs to be connected to a vacuum/boost source, have 5V power/ground ran to it as inputs (probably could borrow 5V from the current MAP sensor), then it has an output that will connect to the dash logic interface.
