What other details would you like? Its a 1991 HDJ80. Everything in the vehicle operates perfectly except for the dome lights and the dash clock. Dome fuse is intact. Bulbs are intact. Dome lights do not work in any switch position, with or without the doors open.You provided no details about your truck, so I will take a guess.
Both the dome lights and clock are fed from the 10 amp DOME fuse in the relay block on the left fender. It also supplies constant +12 to the radio to keep the presets.
The fusible link to the DOME fuse feeds several other items that would render the truck undriveable if it were open.
There are no secret relays involved here. The dome lights are a simple contact closure to body ground fed by a constant +12.

Just looking for ideas (grounds, other possible relays, etc) that other cruiserheads might’ve encountered causing this malfunction.
sounds familiarHi, I wired my new head Unit and wired everything correctly (I believe) via the color codes to the harnesses. I turned on my car, the dome light and head unit came on, however, they started flicking on/off and then shut off. Now the dome light won't work and the head unit no longer gets power.
I checked the fuze in the left panel (hood), doesn't seem burnt, any help would be appreciated.
1997 FJZ80, replacing factory head unit with aftermarket. Does it need more power?
Please tell me you replaced it with a new one anyway just to make sure.I checked the fuze in the left panel (hood), doesn't seem burnt,
Now follow landtank's link/advice.So I found it was the fuse. I put a new one in and as I touched it sparked. The dome light etc came back on, but as soon as I put in my new head unit it blew again.
What car?My car only has 180k miles.
Agree, I thought that was the issue as well. So I got a separate harness (given I had use solder splices ) to test it out and ONLY connected constant power, ignition power and ground, and no short. It turned on and stay on for a minute, then when I turned the car off something blew again.Don’t connect the antenna wire of the new adapter harness if it has one.
I thought we were talking about Land Cruisers.
The main harness comes through the firewall and branches out in several directions. These connectors are stuffed into the body in a clump right at the A-pillar near the floor. Pull that out and one branch travels up the A- pillar. Unplug that and if your short goes away then it’s up in the roof.
If you haven't done it already, the factory amplifier needs to be unplugged.Hi, I wired my new head Unit and wired everything correctly (I believe) via the color codes to the harnesses.

Interesting, thank you!!If you haven't done it already, the factory amplifier needs to be unplugged.
You can find it mounted behind the passenger dash speaker. Remove the glove box for access.
