The zener diode plan mo is also good! Post mo dito pag naging successful.

Ang plan ko naman ay plain swithc over-ride lang, para puedeng naka-off din kung ayaw mo ng DRL.
Sir, check mo sa actual kung may naka crimp na wire. I used a tester to verify pin#8 and its consistent with my research.

Actually nasimulan ko na yung zener regulator hindi lang stable, kelangan lagyan ko ng timer for delay. Iniisip ko pa kung comparator or NAND gates kaso natatamad ako, no time eh..hehe

BTW, im already using temporary(temperament kapag tinamad, lol) 3-position rocker switch.



Toggle with key ON -- OFF -- Toggle with park lights

Upper switch for DRL, while lower sw reserved for rear DRL/fog.
