1933gray Posted January 29 Share Posted January 29 Hello all! Just spent the weekend working on rewiring the Buick. Luckily my uncle is an electrician and made more sense of the wiring diagram (and all of the loose/detached wires beneath the dash) than I could. He was a huge help with splicing on the original special connectors and hooking everything up. We just finished the dash wiring harness and after mistakenly swapping connections for the gas tank feed and the headlight, we sorted it all out and got all gauges and the headlights to work as they had before. Now that only leaves two harnesses left (arguably we did the hardest one in my opinion but I guess we will see). I took a quick look at the headlights/horn wiring towards the radiator and I decided to take off the cover off the light switch. And here is where I begin to scratch my head.... At some point, someone changed the old light switch out for a newer one with fuses The original light switch as marked on the wiring diagram had 8 separate connections. This newer one only has six. You can see that a few wires have been doubled up on two terminals. I am unsure what to make of this. My headlights had an early sealed beam conversion done to them (1940s) and I am wondering if they would have had to change the light switch as well? This situation may explain why I don't have a passing beam or low beam option when I use the control knob on the steering wheel, I only have one headlight option: on (I assume high beam) Now I wonder if I somehow track down an original 8 terminal light switch, will the passing beam and low beam options be available again or do the sealed beams restrict me to the single on or off situation... This light switch also complicates the rewiring process some more as ill have to trace back each wire to see what the connections are for. Who knows if this is even wired correctly! Any wisdom on this would be greatly appreciated.sealed beams pictured Thank you! 2 Link to comment Share on other sites More sharing options...
