Vacuum diagram is on the underside of the hood. Pic 4 hose goes to the intake mani, the hose in pic 3 goes to the front port on the little black canister on the passenger side of the firewall. The hose that is in the canister may be from the brake booster and that should go on a port on the back of the intake mani in the center. The connector that bolts to the cold pipe by the throttle body is mounted upside down.
