any ideas does it have 1 or 2 flasher boxes? i also noticed when i checked the 2 wires to the corner marker lamps i found ground on both wires. isnt the hazard lights and the corner indicator lamps on different circuits or on the same circuit? anyone ever had this problem, any advise will be apppreciated. thanks

good call on the combination switch. but it has a replacement on it. got it from the junkyard. thats how i got my headlights and turnsignals on. but im still left with no hazard warning lights. i wish i could find a wiring diagram for it. the one in the haynes manual is not matching up. i searched autozones chassis wiring schematics. about 10 of them still not match for my wiring. wrong colors and extra or fewer wires in the circuits. anyone know where i can get a model specific wiring diagram or circuit diagram for the 88 d21 pickup. 4ylinder-8 plug 2.4l engine it is the model with the front comination lamps in the bumper. i need to get it inspected and drive it but i think it will fail inspection wih no hazard lights. hel[p......
