Is it necessary to move the #45 pin to #26 in the T42 plug on a 2012 E38/T42 setup?. And remove S and T , and move U to S in the trans plug? Is ISS necessary for Adaptive pressure? Thanks!!

 

Here is what I finally found fot a Gen 4 ----At the trans connector----Remove orange, white, tan/blk, light blue, brown. Tie up white and tan/blk as they are not used.
Brown to pin hole S, orange and light blue to a new ISS plug. TCM connector---move #45 to hole #26.
I am going to give it a try.

 

i havent done this swap, but yeah gotta have ISS with the 80e
