There is no ground wire in the van's original harness. Often people will measure the resistance in search of a ground and mistakenly find the dash light or running light wires. Unplug the new radio, then check for a blown fuse.
For what it's worth, I work on a lot of original equipment radios, and there is nothing higher quality than the Chrysler cd / cassette combo radio.
