4l60e prnd
What is the connector on the left side of the transmission that is labeled in wiring diagrams as PRND A, B, C, P actually used for? Used ltswap.com for pulling wires from my harness and this whole connector isn't used. My thought is that it might output a signal to the computer when it is the positions Park, Reverse, Neutral, or Drive like a neutral safety switch. If I am using the 4L60E transmission should I put these back in?
Thanks, Mike Last edited by mighty_mike015; 12-08-2010 at 10:28 PM. |

The purple output wire from the truck runs to the starter and functions just like stock, so no need to complicate matters. Jay

Re: 4l60e prnd
Only thing to keep in mind is if your plan on using a aftermarket steering column (ie- chrome) sometimes they do not have provisions for reverse lights. You will need to make sure if you do away with you neutral saftey switch you can still have a way to hook up your reverse lights....
