I have a th350 in my cutlass now with a full manual vlave body and since my cutlass came with the 2004r and a console i'd like to do a lttile 79 H/O tribute by adding an aftermarket his n hers shifter to my car then buying a plate for the top to make it look like the 1979 h/o did.The shifter has a reverse light switch but no neutral safety switch and i am stumped on hwo to wire these thing up.Can i use my stock NSS and just wire up the reverse light switch?or are both tied in together stock?and what do i wire up for the aftermarket NSS and reverse light switch?
