What does this mean so I don't make a stupid assumption:
"Then disconnect and just tape off the feed to fuse five."

Also, what do you think of those 3m wire splicers to do the permanent jumping once you have tested it to see if it will work?

Thanks...Dave
The left side of fuse number five is the feed. It becomes "hot" with 12 volts when you turn the key on. If you just jumper over to the left side of fuse five with a constant 12 volts, your brake lights will work with the key off, but that jumper will "back feed" through the original feed that runs to fuse five and your ignition light will be on, etc. You don't want that. So, you must simply disconnect the feed by removing the existing wire that goes to the screw that is immediately to the left of fuse five and just wrap electric tape around it. Then you can jumper an "always on" 12 volt source to that screw on the left side of fuse five. Your brake lights do not use a lot of current, so a simple 14 gauge wire running from the left side of fuse one would be fine -- just crimp and solder little ring connectors on the end. The left side of fuse one is always hot.
