i found a hydro pedel setup and swaped it in my truck with the other parts. i didnt see a safty switch on the pedel assembely. is there suposta be one or not? i have converted this auto cab to stick and have the reverse lights figured out easy just plug in to the stick tranny plug. just couldnt figure out the park / nutral safty end of it. pics would be great if you have anything to offer.
