Looking for high quality wire and connector brands.

Looks like nice work so far.

I try to use TXL "cross link" wherever possible. Thinner insulation (lighter) and more strands per wire for whatever gauge you're using. You can generally get it in bulk from places like Del City, Waytek and even Summit. Obviously the more you buy the cheaper it is.

I've done a lot of EFI wiring over the last few years and I've bought bulk wire and connectors/terminals from both EFIConnection and CustomConnectorkits with success. Low Doller Motorsports is also a good source for EFI sensors and related wiring. If you're dealing with Holley EFI, they sell a lot of replacement wiring components themselves, just have to look on their webpage. Don't forget to look into woven/split loom sheathing for your harnesses. Better than tape, lightweight and actually looks cool.

I've started using Deutsch solid contact connectors. The tooling can get really expensive for it but I like that kind of stuff so I don't mind spending the coin. I bought my 'offshore" Deutsch crimper from Maven. The official TE-brand one is double the price. Maven has a lot of cool stuff.

Might want to check out a guy on You Tube named Devin Vanderhoof, he does a lot of really informative videos on EFI wiring and wiring in general. I learned a lot from him especially in regards to tools and the Deutsch stuff.
