Shift Light in Tune Software
Before I get flamed for this question I will tell you what I know first. I know that some of the Holden vehicles come with a shift light. I know this mod works mainly with corvettes. I have done my research and there is not really any useful infromation on this topic with f-bodies.
Now here is my question, what is the output pin on the pcm itself for F-bodies to initiate the shift light. I was going to tap into the wires myself. If you do not know can some one bring up a wiring diagram of the pcm.
Thanks
Tilly
