Default Vacuum hose connections

Can anybody help me out with the headlight switch and wiper solenoid connections. Not sure which lines run from which ports on a 68 and the diagram that came with the new hose kit doesn't spell it out. On the wiper solenoid there is a port on the same side as the plug terminals and two on the opposite side. One goes to the override valve and the other to a tee to manifold vacuum. I think the manifold vacuum goes to the port on the plug side, but am not positive, and a cap on one of the two ports on the other side and the other port to the override valve. Seems logical, but that is not always how things work out.

Here ya go, kudos to Willcox for the schematic. Pay close attention to the vacuum source connections, always go to the port closest to the pull **** on the headlight switch and the override switches. On the solenoid, vacuum source to the connection side, and the 90 degree port on the other side goes to the override. DO NOT block the straight port on that side, it is a vent.

Thanks for that great schematic and the quick reply. Merry Christmas
