Hello,
My headlights stopped working the other day so I started looking into it and found an absolute mess of a wiring job from the previous owner. Does anyone have a wiring schematic for a 1983 sj410?
I don't see a headlight relay so I'm thinking it's either the switch itself on the steering column or I've got a open wire somewhere
Any help would be greatly appreciated.

I don't have a wiring diagram for the SJ410, but Suzuki at that point in time was not using headlamp relays, they seem to have started around 1996, I would suggest a visit to Ack's FAQ where you can download the diagrams for the SJ413/Samurai and I'm willing to bet you'll find the light wiring to be identical.
