have a 01 grand prix gt 3.8 non turbo. I want to swap my anolog DIC with a digital DIC from a 01 gtp. I was wondering if someone could walk me through the process thank you this is my first posting on this website.

the first thing you'll want to do is pull out the current one, and check back around in the dash and see if the digital plug is there... it's quite common to have both plugs in the dash... if its not there, i know there's a thread here with a link to the wire harness routings that need to be done.... if i find it, i'll post it up.

Well, the FIRST thing you need to know is that not all model year DICs are interchangeable. 1997 and 2003 are unique to themselves. 1998 thru 2002 will interchange. The 1997 cars require an additional wire be tapped into the instrument cluster header. You can pull a pin from your analog DIC header and insert it into the instrument cluster header in the appropriate position. Below is the wiring diagram for all the years. Note the 97 changes on the right hand side.

So to switch from analog to digital in my 03 do I have no other choice but to use another 03 dic?

Correct. You can ONLY use an '03 DIC.
