I just think that in many cases, things would be a lot cleaner if I could simply attach a pin to a brand new wire and insert the pin into an alarm harness plug. I've been unsuccessful in searching for a place to buy these pins, so I was wondering...does anyone know of a place to buy these wire harness pins (for DEI alarms?) Are these pins even sold to the general public? I'm also looking for the inline fuse holders used in DEI alarms, if anyone knows of a place to buy them.

Any help would be appreciated, thank you.

The fuse is not being "extended;" I'm moving it closer to the power source. Out of the box, the fuse on the +12[V] input to my alarm/backup battery is positioned close to the wire harness plug. A short to ground on this wire can occur either upstream or downstream of the the fuse. If the short is downstream the fuse, then the fuse will blow and the wire will be protected from a current overload. If the short if upstream the fuse, then the wire may be overloaded and a fire may occur. Relocating the fuse close to the power source is safer because it minimizes the amount of upstream wire.
