Which map sensor and boost solenoid are you using? The dodge factory map sensor should plug into the stock location on the top of the intake manifold. If you are using the AEM 5bar map sensor, best bet is to make or buy an adapter to repace the factory map sensor. then you can use the stock wiring for the hook up.
This is what i did. I also made a small aluminum adapter plate with a 1/4 NPT threaded hole for the AEM 5bar with an o-ring to seal it to the Intake Manifold.

I also used a GM boost solenoid, I can look for the number for you later, but that also used the factory wiring. works great.
