Default Which Fuse?

2000 GCL! We installed one of those insurance drive and save things where you plug in a diagnostic instrument. But the fuse for that plug must be blown, as no light in the drive and save comes on. Any Idea which fuse powers this plug? NoRuts

I believe the diagnostic plug is wired directly into the PCM.

Try running a diagnostic scan from the plug. If that works, it's a problem with your monitoring unit.
