Get a tee fitting for the size of the vaccum line and connect the advanced line into an existing line from the carb. Worked for me on one of my old cars.

1. Set parking brake. Shift automatic transmission to Park or manual transmission to Neutral. With A/C off, start engine and attain normal operating temperature.
2. With ignition OFF, connect an ignition timing light and a calibrated, expanded-scale tachometer.
3. Disconnect 4 " and 10 " Hg (CEC System) vacuum switch assembly wire connector (located at top of valve cover). Disconnect and plug distributor vacuum advance hose.
4. Start engine, increase engine speed to 1600 RPM and check ignition timing. Adjust timing to specification listed on Emission Control Information label (if necessary). Tighten distributor hold-down clamp and recheck ignition timing.
5. Turn engine off and remove timing light and tachometer. Connect No. 1 spark plug lead, if disconnected. Unplug and connect distributor vacuum advance hose. Connect vacuum switch assembly wire connector.
NOTE: If timing light has an adjustable advance control feature, turn control to OFF position.
Timing is set per the emissions tag under hood.

In late model vehicles with an Electronic Control Unit (ECU) combined with multipoint fuel injection, the ECU takes inputs from several sensors (engine speed, throttle position, coolant temperature, emissions & air temperature etc.) and adjusts the quantity of fuel to the injectors and also the ignition timing to achieve optimum engine efficiency. Therefore, a vacuum advance system is not needed beause it does not perform as effectively as the ECU derived timing calculation.
