i have always HATED the "Christmas tree press-in clip" style zip ties on factory harnesses. just a pain, never reusable, etc. well while working on the wife's vette i finally bought a bag of 100 of em and i'm starting to really like them. now that i can just cut em off n replace they are super handy. 1/4" hole, super secure, done.
also, this cheap split seam loom from amazon is way better than that old plastic corrugation stuff i've used in the past.
