No headlights. Can find a wiring diagram

[Lola]

04' Sedan. Light Wiring diagram and interior fuse box relay layout. It's weird I found the fuse layout if the interior fuses all over the place but I can't find anything on what those interior relays power....
everything else in the car works. Running lights work. No headlights. Low or Hi. Fuse, Low & Hi Relay an the switch are good. I jump the relay and they work. Low and hi. I got it narrowed down and currently hot wired to work normally but haven't found the true problem. There is a junction box in the engine fuse compartment, it's a white plug closest to the fender, a brown wire comes from that into pin 85 in the relays. I ran a jumper from that to power and the headlights work normally. There's a dozen wires on that white junction block and I don't know what wire is the normal power supply to follow. Tracing electrical gremlins without a diagram suuuuuuuuucks hahahaha

Good luck. It should not be too hard now:

Thanks !!! From the diagram it looks like fuse 18 would cause be problem but it's good. Tested every fuse with meter, continuity unplugged and volts on both sides plugged in. It has to be a bad spot on that #1 brown wire or a bad terminal on one if it's ends or a bad spot in that SP101 junction block. I can't wait to get off work and check it out. Now I know there isn't another component in that circuit like a random relay or fusible link or something. Now it's easy easy. This forum kicks a$$

They work with a temporary positive jumper into the brown wire pin 85 in the Low Relay. Low's and Hi's operate normally. So I need to find where the break is in the original line. Brown wire.
