Tape vs split loom

I personally use cheap black hockey tape. If electrical insulation is required, I use heat shrink or good electrical tape first. I do not believe crimp connectors are to be feared or avoided if you have a good crimper and take care to ensure there are no errant strands of wire sticking out. While wiring my car, I have tended to wire things up sloppy to ensure it all works then go back and clean it up right once it all is proven out. One thing I have learned is make sure all your add ons are done before doing your final wiring clean up. I am on round 3 of cleaning up the wiring under the hood.
