Need recommendations for high quality wiring components

[Rotorcraft]

Just about to start wiring up the dash with the Ron Francis harness and vintage gauges, looking for recommendations for the best shrink wrap, connectors, etc, and where to purchase ..

Any other wiring tips appreciated. Thanks !

Radio Shack and Home Dept; HD has the heat shrinkable butt connectors (maybe not as perfect as soldering, but work and look good).
