Does anybody have info/schematics/manuals for this unit? I haven't located any info online. Further information in Conversions forum...

No luck

Thanks for the reply...but none of those sites list the J15, much less have schematics/manuals for it. As I said, I've scoured the internets pretty thoroughly trying to find info. Any other suggestions? I was really hoping for an actual diagram instead of having to manually trace it out.
