Working on a 29 A pickup, i installed a new headlight wiring harness and im having problems. Does the lever need to be in the staight down position for off, and does it move left and right. I dont know how the switch works.Where should the lever be for parklight,bright,and dim. This A does not have cowl lights. They sent a diagram for the wiring, but nothing seems to work right.I have wired many cars, but this has me going crazy. Anyone have a photo of the diagram for the 29 pickup.
