Tailights and dash out?

[Jibha]

Hello, thank you in advance for any help you may be able to provide.

I have a '91 4x4 with a 3.0 V6. I use this truck mainly for work, but also to haul my antique travel trailer around.

Anyhow, I was trying to repair the tailights on my trailer, and using the truck to test them. My trailer has a 4 wire system, so I have a U-Haul dohickey that makes sense of the Toyota rear lights, which as I recall is maybe 6 wire? I'm not sure, I didn't hook it up.

Anyway, I was testing the trailer lights and I think I had the trailer lights grounded. Now my tailights don't work, as well as dash lights. Turn signals and brake lights work fine. I bought a manual to help me figure it out, but no help. All the fuses under the hood look good, but none of them say they have anything to do with the tailights or dash lights. Is there another fuse block somewhere? The manual I bought said later model trucks have a fuse box behind the glove box, but not mine. I have a hard time believing that the rear lights would be unprotected by a fuse. The wiring diagram seems to indicate that it's on a 15amp fuse, but it doesn't tell me where it is.

I guess my main question is if there is a 2nd fuse block, beyond the one under the hood?

Thanks again for any insights,
Joe

Driver side under the dash to the left. There should be a plastic cover that you take off and the fuses will be right there.

Go to eBay and get an adapter for a trailer wiring harness. There is a seller named


davidzot21 that sells them for $8.99

Gotta be a fuse, happened to me a while ago in an '89 240. Had no dash lights, or tail lights, but everything else worked fine.

Thanks for the help. I found that darned fuse block. Why they don't label it I don't know, but it sure will be nice to drive at night again.

The fuse label is on the back side of the cover you had to take off.

I think they should emboss "fuses" on the outside of the plastic panel. After looking at the fuses under the hood, which is labeled on the outside of the cover, the next place I looked was under the dash. But I didn't notice that cover. Every other vehicle I've owned says "fuses" on the fuse block cover, except my roadster, which didn't come with a cover, even though the fuses are in the glove compartment. That is even stranger.

Thanks again
