Default L98 to LT1 conversion help please.

I searched but could not find....

I have a 1991 Coupe. I recently fell into a built engine from a 1995 LT1 (rebuilt to LT4 specs, Hot cam, 383 bored, New aftermarked heads, etc) complete with harness and ECM. I also have the LT1 instrument cluster and Driver control panel.

My question is this. Do I need the 1995 CCM? What years would be compatable? I've been told the dash wiring harness is the same from 1991 thru 1996. Is this true?

Should I also put in a 4L60E trans or keep my TV cable and 700R4?
Anything else?

The dash wiring is different you'll need a new cluster (94-96 and a new BCM(94-96). A FSM for each year car will help you immensly.
