OK, that's a good start. So I need a relay for the 7 pin to the starter, something to take the place of the clutch switch (switch that won't allow it to start with out clutch pressed)
I can read diagrams, I just don't know what key words to search to find them. If done been through every thing that looked us full on Google searching "4l80e neutral safety switch" "nv3500 4l80e/4l60e swap" etc etc. But still can't find any thing. Mostly the harness pin out pops up but that don't do any good.
