Anyone ever use these wire connectors?

[wyly]

I had seen them in my favorite parts source before and thought it was gimicky and I bought what I was familiar with. That was last year, this winter I was tracking down an electrical issue and one of the tried true types had failed. So I gave the new type a try, a couple minutes getting the wires prepared a few seconds with a lighter and it was done and I'm converted.

Those "snap-together" connectors should never be used on vehicles, moving machinery, or anywhere there's vibration. Scotchlok is the most common brand name, and even through they're often supplied for accessory wiring, they are evil and wrong for vehicles.

Dyna ignitions, for example, come with Scotchloks in the kit, which is just a mind-bogglingly awful idea. They're very cheap, they're easy and fast, but are guaranteed to fail. I don't know why Dyna does this.

Ah so! ..yes.."scotchlock" looks like the things I was musing on...Sounds like you've tried them!

I think we have ALL had a bad encounter with those stupid Scotchlok's. I'm pretty sure the instant you lock them shut, they start the corrosion process. Almost every vehicle I have ever bought with a trailer hitch, has had these hacked into the tail & brake light harness.
I typically use the bare crimps with some shrink wrap. Hasn't failed me yet.

Cost might be the only reason I don't use these solder ones. I'm a cheap bastard when it comes to this stuff...
