Hello - I'm getting stuff together for my next swap. I have a funky custom Corvair, currently with a transverse 3.8 rear/mid. (out of 97 Olds) Prepping a L67 package - have motor from 02 Bonneville, trans and rest from 98 Regal GS. Actually have brain and engine harness from both motors, but have complete vehicle wiring, cluster, etc. from Regal GS.. Wanting to understand what I'll need to do with harness, etc. And, what (if anything) I'll need to have done to the PCM. I stumbled across the discussion of CASE at the Intense site, that lead me here. So, more stuff to learn...
