this, and the reverse light tapping. Other than that, you dont need any other wiring. I didnt even connect the reverse lights to the tranny, I made my own seperate switch for it (so I have fun messing with people) :rofl:. the way you rig the park/neutral "switch" is by (IIRC) connecting pin numbers 5 & 7 together. i can take pictures for you if you'd like. The swap was semi-easy, just make sure you dont strip ANY bolts. Trust me, you dont want that happening at ALL. Good luck :thumbup:you also have to rig the park/neutral switch from the automatic transmission and the light on the cluster for trans failure has to be removed.
