i have been preserving a 1983 hilux and while the truck was apart for paint I replaced the headlamps, now headlights won’t come on. They worked while truck was apart. I jumped the headlights at the fuse box and they come on but not with the signal switch. I took the steering wheel off and found two wires that had come loose but they are for the horn, I resoldered them. Parking lights and signals work. Any input would be awesome, thank you in advance.
