TheJigsUp.net offers a great inexpensive tool that provides that third hand. Made of milled aluminum, the jig holds all types of connectors steady while you solder, and it dissipates heat quickly. Bullet connectors at 3.5mm are held in the drilled receptacles and anything smaller or larger can be clamped in place. The clamp will easily hold bare wires through large 45-amp connectors.
