What is the best way to make connections with very fine wire? I have some NJI signals with wires coming out that almost look like human hair--well, okay, it's not that bad but the wires are tiny. I need these to go into an RJ-45 adapter connector with screw-lugs that clamp down on the wire. This is not making a reliable connection. Even getting the insulation off will require finesse--a wire stripper or side cutters carefully applied is out of the question. Soldering to this thin wire will be very touchy.

Do I reinforce the wire at the point where it goes into the adapter? Or ???

I use an Exacto knife with a new blade to remove (carefully) insulation from tiny wires. I cut all the way around the insulation without cutting into the metal wire and then pull the insulation off with my fingers.

You can then fold the wire back on itself and twist together to make a "thicker" wire that the screw lug can grab onto.

I have also used solder to attach a thicker piece of wire to the end of the thinner wire, so the bare end of the thicker wire goes into the screw lug connector. Braid the ends of the wires to each other and use a holder with clamps to secure the wire(s) and solder carefully and quickly. A good electronic solder that melts quickly and a quality iron are your friends here. Finish with some shrink wrap.
