Patient: 1958 Apache short bed side step.
Problem: Driving lights come on, turn signals work, when driving lights are NOT on brake lights work...when lights are ON brake lights don't do anything.
Here is what I did: Had a pair of crappy iron cross tail lights on the truck when I bought it. I took them off and modified stock tail lights to add another two wire socket and bulb...because that is how the after market units were wired....except they had a single wire socket for the second bulb (the second bulb was the flasher/turn signal bulb and it grounded to the housing.
So, I "cleverly" wired the main bulb as it had been, then wired the third wire sticking out of the back of the truck, the "flasher wire," to the new two wire socket and the other wire (which I presumed to go to a ground) I connected to the same ground wire as the main bulb.
OK, what did I do wrong?
