Tacho Signal Levin Coupe with pics

Yes, crimp connections are the best, but I doubt many people would bother with the investment in tools and such (I got a few from work I can use these days though).
@Thomas: Tacho signal is not something critical, so if the connection should fail it's no biggy. I much rather see these things then cut and twisted wires when I poke around a cars wire loom. These can easily be undone. Dont ask what they will do to longterm durability of the wire beneath it though, but you get that problem with many methods once you've removed the insulation.
