You do not need the two wires in that two-pin connector. Those are for steering wheel controls, speed-sensitive volume, and things like that. The radio that uses that plug usually is the CD/cassette combo radio. That is the highest quality radio I have ever worked on. Most of those systems were the Infinity systems that include a remote amplifier. When you downgrade to an aftermarket radio, that amp has to be bypassed.
It is important to understand that unlike Ford and GM radios that must be used with an amp when the system requires it, you can use any Chrysler radio with or without a Chrysler amp. Theirs do not increase volume or power. They are used strictly for tone conditioning for the shape of the vehicle. That way one radio model will work in many vehicle models. If you do or do not use a certain radio with an amp when required, you will either have too much bass unless you turn it all the way down or you will not have enough bass unless you turn it all the way up.
There are seven terminals in the original radio's black plug. If the last wire is missing, the farthest from the key way, there is no amp in your vehicle. If that wire is there, it is also for a power antenna. There has to be one of those, an amp or a power antenna, on your truck if there is a wire in that seventh spot. That is used for the turn-on signal for the remote amp. You can try connecting it to your new radio's "power antenna" wire. That will turn the amp on when the radio and ignition switch are turned on, but I do not know how pleasing the tone response will be.
