ISO harness doesn't fit

[PboroRyan]

Hi all, done a quick search and couldn't find anything.
I've got an ISO harness for an aftermarket stereo, everything else fits bar the bloody ISO harness!

On the car side i've got this:

and on the stereo side i've got this:

Where the pins are on the ISO side should connect to where the two blue fuse looking components are - do these need to come out? Additionally, the pins on the ISO harness are all vertically in-line, but there's one pin that doesn't seem to fit anywhere?
TIA

Its right that dude. The 'stray' pin plugs into pin 12. They should fit together no problem at all.

you know when you realise you were being a moron? This was one of those moments. Didn't realise the pins slotted down the side of the blue rectangular bits
