Does any one no any one that makes a head light haeness that makes the head lights and dash lights brighter for a 1969 Plymouth GTX.
 
there's a few companies that do a relay system
to get a full 12 vts & the switching goes thru them

maybe also try looking at http://www.madelectrical.com/
or call the guy he's a good dude

Year One use to sell a headlight harness upgrade with relays etc.
for HID's either or just more power to the lamps etc.
from M&H Electric IIRC http://www.wiringharness.com/
I think they sell mostly directly exclusively thru Year One (?)

we had a guy here @Propwash did a harness system for his headlights too
69 RR he was building, his beautiful black beast
If you don't use the HID's you don't really need the ballasts or diods
Propwash's schematic

or like this maybe, got off the RR forum a while back

Mopar 68-70 Headlights Relay Schematic to help brighten headlights (1) RR forum.gif


I haven't tried either of them

I went to Halogen lights & a higher 75 amp Powermaster Alt.
haven't done the relay mods "yet"

I did add a 8ga wire from the 12vt 1/4"- 20 off the alt. charging post
to to main lug 1/4"- 20 on the starter relay on the firewall
to help shorten & carry the load, it seems to be fine
not excessive added amperage strain the underdash area
or the bulkhead connectors

good luck
