Location of connections and components

(A) low / high beam and parking light connections rear running light and stop light connection.

Pin numbering of wiring harness side bbs unit connection.
Checks
The front and rear parking lights use led light units and receive a 12 v power supply. Power the parking lights with an external 12 v power supply to test function (connect correctly as indicated in the wiring diagram).
Check congruence of the ground connection on the running lights.
Check that the parking lights receive 12v arriving from pin 7 of the bbs.
Check the integrity of the electrical circuit and connections (short-circuits to ground, short-circuits to vdc, open circuits).
If none of the aforementioned tests identifies the problem, replace the bbs.
Note
Check integrity of electric circuit - short-circuit to vdc = with dashboard on, using a voltmeter, a voltage is measured between the wire tested and ground.
Check integrity of electric circuit - short-circuit to ground = with the battery cables disconnected, using an ohmmeter, continuity is detected between the wire tested and ground.
Check integrity of electric circuit - open circuit = with the battery cables disconnected, using an ohmmeter, no continuity is detected between the two ends of the wire tested.
