Headlights Cut Off
my switch, 50 year old, used to have days when the headlights didn't work, they'd just randomly go off and id have to stop and rig a "jumper" at the bulkhead connector to get them on... and then weeks when they worked fine so i presumed some kind of breaker in there
i have factory fitted relay for headlights and some kind of lock out setup by a second factory relay to only allow driving lights if headlamps are on high beam...
so even with the relays the switches can go bad...maybe 2 relay coils pull the same current as 2 candle power sealed beam headlamps do, and therefore trigger a well worn thermal breaker
my experience is once it has done it once, it will do it more and more until you can't trust the lights will come on and stay on for more than about 5 minutes
the switches came with 7 connectors or 7+ 1 grounding tag, and 9 connectors
you car will be wired for one or the other....
the 7 connector switch is not an 9 connector switch with 2 missing. the pin outs are subtly different. for at least 2 of the pins in the middle they are linked one version and not on the other
if you have the big plastic plug on you car with all the wires in it. I believe it will physically fit either switch.... which doesn't help
if you want the big plastic plug, they often melt, you can get them new from hemi performance in australia
