2007 5.3L starting system wiring????? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have been building a 68 stepside with a 2007 5.3L/4L60 setup for to long now..LOL. I was just finishing up the wiring, I though, and now I am unsure of the starting. A little brian storm--- the PCM enables the starter when it sees everything is good. The problem I am facing is the PCM won't see the ign. input because I am running the 68 ign. switch and the 2007 ign switch feeds into the BCM and then the BCM relays the message through GMLAN high speed network. Now if I just feed the starter enable circuit from ign switch will it start.. I know I will need to dissable Passlock and other stuff, I have EFI Live to do that, but at this time I am just worried about the wiring..

Thanx for you input guys..
