Funny you should mention that! I'm trying to replace the factory head unit (P/N 08A01-101-230) in my 91 Civic DX 3 dr with a CRAIG model DR-3641 AM/FM Cassette player.  The original failed, and I need to put something in the thing before I sell it.

I noticed your, plight and so I direct you the following image:

Anyways, Maybe someone here could help me with my wiring problem as well.

This factory radio diagram has two leads for which I don't understand the purpose:

SWD +B  and +B (backup) 

Does anyone know what these leads are used for? What do the abbreviations mean?

Thanks,

And 91, I hope the diagram is helpful.
