I stand corrected. In my experience the way they screwed together mashed the exposed wire tightly against the metal cone and didn't slip out at all when I tugged on them pretty hard. Also,you could leave one end connected (and thus protected from your goofy ass accidentally blowing a fuse) while you strip/prep the other wire you're putting to it. I had no issues with them. However, I won't argue against a good solder as the best connection. I just happen to really suck at them and these presented a decent option.

solder and engine vibration = bad news bears - I would solder AND maurette, then electrical tape the base further down the wires if I was that hardcore, but butt connectors and heat shrink tubing do well for this application.

Facebook album permalink (in case the images don't show up in the future).

Okay Blair! Three years later, and I've got those pics for you.

This is how I crimp a butt connector. This same method applies if you leave the plastic sheath on, but for my demonstration I used heat shrink instead.















This is where my method is different. I use the pointy end on the split in the connector.


Even if you get the most horrible looking crimp, you're still in the clear because of the next step.


This is the important next step.


One side done.


The other side.


Again, this is key.


Try to tug that wire out. I dare you.






If it had the plastic sheath on there, you'd be completely insulated by this time. Even minor breaks in the insulation get covered up during the last step.


You didn't forget to slide the heat shrink on earlier did you?






One more for good measure.

no offense but this should be made known that this is possibly the WORST way to do wiring. NEVER EVER put all your solders/butt/crimp connections in the same place, it makes for 1 huge unmanageable bulge. these types of things are always better off to be staggered as to cut down on the mass. Also i am 1 of those people who are mostly against crimps/butts.

eno I hope you don't mind I moved your soldering advice to the only soldering advice thread we have right now (which needs work obviously). You mind if we keep this thread only about crimping please?

No offense taken. You'll be very glad to hear I've been staggering my joints for a very long time now and I've echoed the same advice on many occasions. It is worth repeating though.

It is hard to see, but that joint is staggered from the other one. Maybe not enough for my liking, but it was a rare instance where the length of wire didn't lend itself to more stagger (I wanted the most shielding possible and I'd have to have removed shielding to get a better stagger), and it was a very light part of the wiring harness with plenty of other scrimps staggered all around it which gave me nowhere else to go. If you keep watching my thread for updates I hope you'll find the staggering to your liking.

I'm pretty sure there is a different thread for this argument. I'll look for it.
Edit: Here it is. You should post in here. http://www.sr20-forum.com/general-sr20/28409-wiring-splicing-tips-solder-vs-butt-connector.html

To negate the OP, sorry Blair, but a solder connection is not as good as a high quality splice. In Naval/Marine Avionics school, they taught us to use splices, but not the cheap splices one can buy at Napa, we're talking aviation grade splices with the correct crimp tool. It's a more reliable connection (can't muscle it apart with force) and provides better continuity.
