97 0411 swap then ls swap

Post by TrendSetter »

Hi,
I have a 1997 w4500 liftmaster with a vortec 350, same as a tahoe or anything else that year. I already swapped to a 0411 pcm from the black box and the truck runs as well as you could expect. Next step is a LS swap. I plan to only swap the motor, keeping the existing 4l80e.
Are there any threads that outline the harness mods for this? I know i need the coil wires but im not sure what else and id like to get all of the pieces and a plan together before taking anything apart.
all the threads i could find involve replacing or heavily modifying the old harness but id like to just use whats there since it must be close considering im already running the correct ecm.
any help is appreciated.

dave
