option 1) graft LT5 ECM into existing harness/dash (need Leon's help here)
option 2) use 89MY 8K dash (CCM on prototypes? require prototype dash harness?)
option 3) use CCM w/90MY dash (not certain what other parts would be required)

btw - my 89 has FX3, i ordered it w/every option sans tpms.

you DON'T need the CCM AT ALL

I see you are still a bit confused..

the CCM is ONLY for the 90-newer style dash, it is not needed in your 89 at all, whether you have a L98 or LT5 or LSx

you need to compare the engine harness connectors at the firewall. get them to mate..
