Vacuum routing help Hey guys, I am in the middle of an engine swap, and I need help hooking up all the vacuum hoses from the LS1.
There are lines off the tranny, the motor, and back through the firewall, with a couple of what looks like check valves. If anyone has a diagram or any insight that would be helpful, as I am stuck here.

Your HVAC controls are vacuum controlled. The check vavle meets right at the pcm. You need the constant vacuum side to be going into the vacuum line coming out of the fire wall. Are you sure some come off the tranny, is it manual or automatic? The vacuum lines should be coming from behind the intake.
