What all do I need to do to swap a 4L80e into my 98 Z71, electronics wise? Do I just need a harness/or repin the current one and do a 4L80e segment swap like you do on the LSx?

If so, anyone got a 16263425 OS 4L80e tune?

PM me your e-mail address and I will send you the wiring instructions----There's not much to it. I am not sure if I have a 98 4L80 calibration or not. I will check tonight when I get home from work.
