I bought a harness off here specific to lt1 but it has 4 l60plugs. Im going to run the 6 speed.what do i need to do wiring wise?

 

Anyone went from a 4l60e to a t56? any insight or write up for it?

 

You'll have to get the plugs for the reverse lockout, and reverse lights, you'll need to wire up a power feed for the reverse lockout, the reverse lights go through the C100, your vss connector should be the same, and you'll want to program cags out in the pcm unless you want it to stay functioning and then you'll need to wire it.

 

i do haveq a pcm for a 6 speed already.
