I purchased a brand new interior wiring harness for my 67 skylark. At the time, I ordered it for column shift. That was a few years ago. Now I have changed my mind and am going with a floor shift automatic with bench seat. Yeah, I know, strange but "reasons". I will probably use one of those Lokar linkage setups or something with a bench bend shift lever. My question then is, what wiring changes need to be made? I assume there is a neutral safety switch and reverse light switch. Is there a plug and play type adaptation for this, or is it just a matter of pulling wires and secure them? Thanks for all info.
