Hi Neil,

The Pico connectors are kinda crappy.  These Tyco/AMP terminals are just like what the factory used.  The part numbers I reference are the Tyco/AMP part #.  You should be able to find a supplier in Canada that has the same stuff if you look around a little bit.

Here is a good (and very affordable) ratcheting crimper that does both crimps at the same time.  Mine lasted for several thousand crimps before it failed.

If you want to get a nice crimper with multiple dies, this one works well:

While you are spending money, grab a good wire stripper if you don't already have one:

That's some of the stuff I use to make my relays https://sites.google.com/site/vanagonheadlightrelays/.  I'm sure the same gear will work very well for you.

Hi all.

This may also apply to Pico US, but for Pico Canada, these locking
type push on connectors:
