Does the unit that your installing allow for multi speed tach programming ? As far as the parking lights go, go this this post and at the bottom of the post Chris says there is a way to catch the parking lights without the resistor and relay : https://www.the12volt.com/installbay/forum_posts.asp?tid=2005&KW=dodge+Caravan+lights

The post is for the 2002, but it is the same for the 2003 Caravan as well. Hope this helps you out and post your results.
