Front marker lights turn off when headlights turn on

[mkst65]

Hi, I,m new to this forum and just lookin for some help. I bought a 65 longbed recently. Someone had put a tilt steering column in the truck (worst hack job I,ve seen in awhile, anyway..). I finally got the front marker lights to come on and they no longer come on when I hit the brakes! Next problem is that the front markers turn off as soon as I turn the headlights on. Does anyone have any idea where else I should be looking? The only obvious damage to wiring is at the column, which I have been trying to repair. I think it may be a ground or short issue, but not sure and not sure where to look. Never had this body style before and have wanted one for awhile. Any help would be greatly appreciated, thank you.
