Help to undue this electric wire joiner.

[AXO66]

I managed to loose my rear amber side marker .( another story). Got a replacement .However the old wire ends in some sort of rubber water proof join to the feed wires.
See picture.

How do I take this apart and change the old wires for the new ones?

Thanks in advance .

As they are the same colours going in and out, That to me looks like a terminal, not the wires to your side marker but, if you look closely to the end opposite the wires, it looks as if there is a space for an electrical screwdriver near the hole or indentation?
The other one with the yellow and white wires looks more like the correct one and that, maybe, the earth?

Thanks for this quick reply.
My terminology is probably wrong.

The 2 side marker light wires go into the terminals/ connectors . I just couldn’t see how to get them open and see how the wires are connected.

(The side marker wires no longer have a marker on the other end and are black and white in colour , but not that visible on the photos)

So maybe it’s just a matter of jiggling them open with small screw driver ?

Now wondering which is positive and negative .

They look like insulation displacement connectors very similar to those used in the telecommunications industry. Most probably jelly filled to prevent corrosion.

They are not openable, all you can do is cut the wires as close to the connector as possible and reconnect any new items with whatever type of connector you decide to use.
If your side markers are normal filament bulbs and isolated from the metal bodywork then the polarity is irrelevant. Some LED versions are still polarity conscious others are equipped with circuitry that allows for incorrect polarity connection.

I think they are just that

Multi/volt meter.
Touch to both wires. If the meter shows a minus sign before or after the voltage it's the wrong way round.....should just be the numbers, no minus sign.

Thanks folks . The marker is a Joken LED marker. From what I can see the terminals looked sealed and are are fastened to the underside of the boot floor, so exposed to the crud from the rear wheels . Obviously the need to be totally sealed . Think I’ll take it to an auto electrician as one of the terminals has 2 wires and the other has 4 from memory , leading to the rear light cluster and the marker wires are taken from that circuit .
Thanks again.

They are probably a version of these crimps

It might be an idea to leave these joints alone and cut the wires nearer the marker if it is higher up and won’t be getting splashed etc. Wago do a good range of connectors.

..……..of course.

Just join the old existing with the new wire from the unit.
Thank you.

They certainly look like IDC connectors. I’ve gone through thousands of them in a previous life. The can be opened if you squeeze them either side with a good pair of pliers. It will destroy the connector and the wires will pop out. You still need a to cut a bit off to get a good clean new bit of wire to connect on to but when they are tight on length it gives a few mm extra to play with.
