Miniature 2 way connector

So i'm looking to source a tiny two way connector for my number plate light bolts.

The bolts pass through a 6mm hole in the rear bodywork, with the wiring sticking out the back. The connector therefore needs to fit through an 6mm hole and through an M6 nut!

I'll need to reposition the lights after IVA so I need a solution that allows them to be disconnected from the loom. Access to the insider of the rear of the bodywork in the Fury is terrible, so depinning a connector and passing the terminals through the hole isn't really an option.

Cutting one of the wires shorter than the other and fitting a bullet to each is the best I can come up with, but even that will be too bulky to pass through the hole.

Any ideas?

can you cut the wire, push it though then join the wire again, with a bit of heatshrink over the join?

I had considered that but it would be really difficult to do on the Fury...I can only just squeeze my hands between the rear tub and the chassis to get access to the back of the numberplate.

One option would be to extend the wires before installation, so that they can be accessed from the rear wheel well....this might well be my best option actually....

How about these, as used for battery connections on RC models... not sure if they'll fit a 6mm hole but can measure one later if you want..

They are decent connectors - will certainly take a few amps, as they are used to connect the battery on smaller multirotors. I doubt that they'd go through the bore of an M6 nut though...
I haven't seen a smaller connector, but in a similar situation I've used bullet connectors and fed them through small holes one at a time. The tightest squeeze is when you've pushed one through and trying to get the second one in past the first one's cable. The R/C folk use very small bullet connectors, so worth a look there. This shop has a good selection of connectors at low prices (although P&P bunps the price up for small orders).

This would be my approach as well. slice the wires, pass them through the hole and the solder join to more wires with some heatshrink over the joint to protect it.

Thanks for the suggestions. Looks like I'll need to either go with the bullets or cut the wire and feed it through....or maybe both. Access to the rear tub area behind the number plate is very difficult, so I'll need to extend the wires in any case so I can get to them from the rear wheel well. I don't think a crimp splice will fit through the nut either, so I'll need to solder the wires to keep the joint slim.

I used the small Japanese bullets with weatherproof sleeves. Works well.
