Dan:
If you are going to use relays to handle the increased current (power), 
the signal to the relays ( pull-up) should be the same line that 
previously lit the headlamp bulbs, but.... the current for the relay 
contacts that eventually goes to the higher power bulbs, should not come 
from any of the previously used wires... it MUST come from a higher 
current source... in a 5000 I would recommend the emergency starting ( 
jumpering ) post in the engine compartment... that fellow has a direct 
line to mr. battery and is thick and healthy ( in a 5000 ) in your car 
I do not know...( you get the idea ) You must not use the present 
wiring for the headlight bulbs... only to pull and control your 
relays, otherwise there is no gain... keep in mind you will also 
increase the temperature in the bulb connecto sockets.... I don't know 
what wattage you intend to use but... IMHO anything over 60 watts 
requires bigger and wider contact area sockets...
Boa noite !
Good luck
