The electronic indicator flasher is connected to the turn signal switch of the multi-function switch through Circuit 44 (LB). Ground is provided to the electronic indicator flasher and the turn signal miniature bulbs through Circuit 57 (BK).
^ With the multi-function switch in the right turn position, power is supplied to the RH front turn signal miniature bulbs, the right turn indicator in the instrument cluster through Circuit 2 (W/LB) and to the RH rear turn signal miniature bulb through Circuit 5 (O/LB).
^ With the multi-function switch in the left turn position, power is supplied to the LH front turn signal miniature bulbs, the left turn indicator in the instrument cluster through Circuit 3 (LG/W), and to the LH rear turn signal miniature bulb through Circuit 9 (LG/O).
