Man it amazing how all these cars have similar problems, when I got my 81 i also noticied that the dims worked but when I hit the brights no lights.... all my parking and blinkers worked great, I noticed a rocker switch hanging out of the underside of the dash, someone had rigged this switch to operate the brites so i just made a nice dash plate mounted a better looking rocker switch on the bottom of the dash and thats my brites switch for now..

Yeah, I thought I was the only one who was having these problems until I found this sight. My problem was the guy I bought the car totally had wired the fuse block wrong he had wires that did not match the head light harness. It is crazy how some people worked on these cars. I will say this, with the help of Ken, I not only learned about wiring diagrams, but I fixed my problem.
