Bruce, I like this tip very much!  Instead of all those funky plastic housings around typical glass-bodied fuses going to accessories, I could have a clean setup.  Thank you!  I will start researching.

 Hi Richard,
What about considering a secondary fuse box (kind of like a sub panel) and secure it in a central spot somewhere under the dash and hook power to it and then connect your accessories to the secondary fuse box directly instead of splicing and dicing?  That way you will know where the accessories are being powered and they can also be fuse protected as well.
All sorts of size and amperage configurations on Amazon or on other automotive sites.

My van is 85 tintop.  Second owner, since 1989.  So I am the DPO.  I've added electronic accessories along the way:  Honda Radio, Audiovox Cruise Control, Garmin GPS, even a switch to activate valve on my hot water/shower setup, hidden fuel pump kill switch.  All works Great!.....until it doesn't, like on latest cross country trip the radio just stopped working while driving along.  Okay....I made the bonehead mistake of "kludging" the connections, kept hop-scotching.  There are primarily three:  Ground, Constant 12VDC, Switched 12VDC.  I just kept splicing into existing things.  I need a better way.....it is definitely looking like an Octopus out of control under there.  I have some ideas in mind, but thought I would ask the gang if they have any tips.  Also....it would be super helpful to have wires of different colors, like they do at the factory; I'm sure I could find at FLAPS, Amazon, or Ebay but maybe you know good source.  My basic plan is to use generous lengths of wire, zipties, and appropriate labeling.  Systematically clean things up.
