These plugs are very similar/same as the audio plugs you use when connecting audio up between sound cards and cd/dvd players in PC's but have faded out now due to sound going full digital

I have seen these plugs on the RS or Farnell sites cannot remember which site i'll try and find them again, sorta found them whilst on site looking for some PLC parts for a customer but got bored when they could not make their mind up ....

Have used for over 5 years never had a failure, I use these in all my aircraft I like to know that every crimp is 100% plus you make the installation neater as you can make them to the correct length etc..
