I have a question I'm doing a swap on my 1988 c1500 I'm swapping a 2001 5.3 and a 4l60 e tranny in as well I'm guess I'm gonna have to use my stock harness for the starter an was wondering if the neutral safety switch on the swap harness would be an issue

 

I dont have the nuetral safety switch hooked up on my swap (2005 5.3 4l60 in a 71 chevelle) and it has not been an issue at all.
