tail lights

[fl_bluebird_1983]

My tail lights quit working, so I started at the breaker behind the
driver side headlight (breaker#6) I have power leaving there. I
checked at the terminal block above the batterys and it is dead
there, so I opened up the dash to get to the switch and I have power
there. With the switch in the parking lights position the dash lights
up green and the parking (tail)lights come on like they should(2 of
the 4 tail lights). With the switch in the headlights position the
headlights come on but no taillights, but the break lights work fine.
My question how does it get from the switch to the terminal block
above the batterys? Is there a relay or some other fuse between the
switch and the terminal block. Also does anyone have a wiring diagram
for the headlight switch. The switch has 6 wires
red= hot
green= hot
orange= headlights
blue= guage lights
black/orange= parking & green dash lights (crimped together on same
lug)

with this setup I'm not sure how you can turn on the tail lights
without using the orange from the headlights, because the
black/orange wires are dead when the switch is in the headlight
position. Otherwise
the dash would be glowing green anytime the headlights were on, but
that would turn on the tail lights
