1988 IDI no brake lights
I have no brake lights. There is no hot wire going to brake light switch. The turn signals work. What do it look for next?

How do you know the fuse is good? Did you try swapping it for another? (just double checking what you did, because sometimes they look good, but aren't).
IIRC, cruise brake switch would be vacuum on an 88, so start at the brake switch with wires, and try to trace which wire goes back to the fuse panel. Like Tom said, one of those wires should be hot at all times, if neither one is, it sounds like your problem is there.
If both switches have wires, then you'll have to trace both until you find where the problem is.

This thread has wiring diagrams that should answer your questions. It may not be exactly the same as your 88 but close enough.
