the 6th gen you want to use is the 98-99 style as the 00-02 the temp gauge will not work right, I dremel tool to shave the clear plastic on the very top of the gauge if you put the cluster up to the 5th gen bezel you will see how much to shave be careful as the clear lense is very easy to crack ,as for wireing you just have to repin the 3 plugs (I cut up a 6th gen dash harness and 5th gen gauge cluster made a jumper harness) and diagram for both cars the 2 problems you will run in is if you have a EX the abs light circut on the gauge has to be moded and the other is the brake light out warning unit in the back right tail light has to be replaced with a 6th gen one or the wire removed .
