parking light

[aichord]

Wiring up rust bucket to sealed beam head lights. My problem is that i have three wires coming into the bucket. I have found the parking light wire, but after grounding the light, there is no where to hook it. The light has three terminals 1 for the ground wire, 1 for the high beam and 1 for the low beam. I have found the following
6 oclock system off
7 oclock parking light wire is hot
5 oclock no wires are hot
4 oclock high beam is hot
tail lights work at 7 5 and 4 oclock
Horn works and brake lights work
So where do I hook the parking light wire to?
I know Stupid question
