I have an '87 cutlass cierra, 3.8L. When I turn the lights on the fuse blows for the running( or tail ) lights. The head, signal and break lights all work. There is a clip on the firewall where I was able to disconnect all the front lights, fuse still blew. I found a clip in the trunk to disconnect all the tail lights, fuse still blew. I checked the wires behind the fusebox and all seems fine. Could there be a relay or something I could check yet or am I doomed to rip apart dash and look for the short there? Please help!

Traces the wire back thru the body from the point you disconnected them to the fuse box , also are the dash lites on the same circuit

Will trace the rest of the harness today and no the dash lights are not on the same fuse. Thanks for the reply.

Turns out the short was in the stereo. I still don't know how exactly but I disconnected the stereo and the lights are working fine now.

An AM radio?, always mention issues that are non standard in your posts.

It was a Delco right? Out of curosity, was it the illumination wire you disconnected?

Just out of curiosity, is the illumination wire a plug with 2 wires, one orange, and one brown?
