Thanks all. Agree the recommendation vs splicing to ISO standard male connectors.

The reason for asking is to be sure I've matched the Defender wires up correctly.

You may be able to see from the photos -- currently the white with orange stripe wire from the loom is connected to the ISO red wire (switched power) and the purple Defender wire to the ISO yellow (permanent power).

In the carcass of the connector there is a solid blue (is that a power line for an antennae?) and a solid red wire (some other form of power?). There are back wires with yellow, or brown, or red or pink stripes. I'm trying to understand these colours on the loom wiring side so I make sure when I connect to the ISO standards I do it right.

Does anyone have a quick summary of each wire purpose or can point me in the direction of a diagram or link that explains ?

Really appreciate the answer so far

If you’re not familiar with the colour abbreviations on wiring diagrams this will help.

The black wires with coloured stripes are speaker wires, be careful to get the polarity correct. You won’t damage a speaker by wiring it back to front but it will sound dreadful!
