I sure don't remember the park lights being on with the headlights as early as 1970. Could be but i sure didn't think so. I was thinking that it was quite a bit later than that.



'68 B-body or at least a '68 road runner did not run the front parking/running lights when the headlights were turned on but the '69's did. The only thing that I found when I was trying to figure out if I had a '68 or '69 underdash wiring harness was one yellow wire on the '68 that shut off the front parking lights and I think that's because the '68's had four (4) side marker lights that may have (by engineering standards???) been determined to be too much draw with the headlights or high beams on?????? "69 models had four (4) reflectors and did away with the four side marker lights.
