Thanks for bringing that up, I didn't mean to imply that I trust them, in fact you will never see one on any of my vehicles. Ultimately it's the customers decision, and when there's no room to get both hands in there without hundreds of dollars for removing part or all of the dashboard, they'll pick the cheap route every time. If I were the service writer that would change, but I'm not. It's never an option except for underdash work. I haven't seen the heatshrink crimp connectors fail, I think the inner glue layer might hold the wires and reduce the cold flow by keeping tension off the conductor a bit
