The small end of the hose attaches to the wastegate solenoid.
The straight hose off of the Y tee attaches to the wastegate.
The other hose connects to the turbo compressor housing brass fitting.
You should also note there is a restrictor orifice, inside the "Y", on the compressor side of the Y.

My 87's OE orifice measured between .043-.048" diameter. Sometimes the wrong size was installed or modified by previous owners.

Also, my pic may be easier to uinderstand than the written description :
-- Upper right hand 45º port goes to wastegate actuator.
-- Left hand horizontal port goes to electric valve.
-- Right hand horizontal port has internal restrictor, goes to Turbo compressor.
