1947 ford parking light wiring issue

[Seth Swoboda]

I've always been able to solve any wiring issues without much problem. However, this time I'm stumped. Another set of "eyes" sometimes helps.

1947 Ford tudor, I can not get the parking lights to function properly. The problem is when I wire the lights into the wiring harness following the color coded wire schematic and I pull the light switch out to the first notch for parking lights they (parking lights) work. When I pull the switch out all the way for headlights and hit the high beams the parking lights come on and no high beam.

I've checked the light switch at the dash, wired correctly. I have the yellow with black tracer from the pig tail on the switch hooked to the yellow with black tracer to the main harness. Some of the wire on the chassis is faded and hard to discern colors, I've checked their proper connections as best I can with a voltmeter.

All thoughts and ideas will be appreciated. I'm sure this is something obvious.
