Just a couple questions on a 4r70w to 5 speed swap.... 4x4

1.) Will I be able to use my factory driveshaft that the 4r70 used, or will the m5r2 make it longer/shorter?

2.) There was someone who wrote up his conversion showing the wiring harness for a e4od to zf swap. He has the esof(push button 4x4) Like I Do. He jumpered a connection on the harness at the firewall that made the esof module think the truck was always in neutral so he could still use the push button 4x4. Can anyone tell me what connection needs jumpered on the 4r70w harness or is it the same jumper as the e40d tranny harness?


THANKS!!!
