The dome lights work but after installing a radio on my 89 XJ, the tailights (brake, park, reverse, license plate), dash, cluster stopped working. There are a couple threads about this online however no real answers specially for a renix.

thanks in advance

Disconnect & tape the dimmer wire, then replace the fuse.

i believe i know what wire you speak of in the harness with all the other radio wires right? which fuse exactly? also what are the chances its the switch or a relay or sumthin in the fusible link after battery?

neonzion

small fuse!? where??

In the fuse block under the hood pull all of em and check them good happened to me after I changed my radio might have small letters like CEL or BUS

The fuses

When you hook up the dimmer wire for the radio it shorts out (and pops the fuse) for the lights in the Jeep.
So:
1) Disconnect & tape up the dimmer wire you hooked up to your head unit.
2) Locate the burned fuse (passenger kick panel (?), I don't know for sure on the old ones) labeled "brake" & replace it.

1989 fuse panel drivers side above left foot ,relays under hood have nothing to do with lighting just leave them be......Did you mess with any wires in rear hatch ?

one of your wires from the radio might be shorting out too.a bare wire somewhere. mine did the same thing.
