I don't follow, you say "Actually hook up the neutral safety wire to the transmission". The neutral safety switch is on the transmission, so take that signal and feed it to what input on the rs4-g5.
Also on the clutch there are 4 type, +12, grounded, two wire short, normally closed need to open when starting.
