The 98-99 cluster has 2 plugs/harnesses (one on the left in the mid-backside of the cluster - the other on the right side of the left connector). The 2000-02 cluster has one plug on the bottom in the mid-backside of the cluster. Maybe it's just set up differently and doesn't matter. But have to make sure.
All of the LH (1998 - 2004, 300m, Concorde and Intrepid) clusters plug in the
same way. There are only two connectors. One on the right and one on the left.
Just like Ronbo said in his post, "The connectors are the two white rectangular
ones oriented vertically near each end on the lower part of the cluster.
The holes in the backing are irrelevant.".
There can be issues with warning lights. For example, if you take a cluster from
and ABS car and plug it into a car without ABS, you will get an ABS warning light.
In this case, where you want to plug an 02+ cluster into a 98, you might get an
airbag warning light and/or other warning lights because of wiring changes made
by Chrysler in late 2001.
