crimp connector sizes

[builder22]

the heat shrink butt connector type

is it safe to assume if the cable fits in to the connector then its fine to use? it's for rear lights on a trailer

got a pack with blue red and yellow, the wire fits inside the red ones no problem, except the earth as its a bit thicker

any time I've seen them used on repairs/mods etc it's always the blue or yellow ones, can't remember seeing the red ones

wondering if there's a reason or if the blue ones are just cheaper/popular

The colours refer to the gauge range the connector is designed for. Does not really matter as long as you are getting a good crimp. I wouldn't use a connector in which the crimp doesn't grab the strands well enough, nor use one in which you are having to force the strands in. For lights I imagine reds are plenty enough for the gauge of the wire. Blues for the earth.

Use the smallest the wire fits into. You'll get a stronger crimp that way.

great thanks

just kinda assumed I'd use blue for some reason but red is fine, and tidier!
