Roof wiring for Baja s2

[Overland Hunter]

Looking for some help regarding installing roof lights. I've purchased a pair of Baja s2 to mount. I've attempted to install them today but struggled with the connection being a little loose. I think the connections on my rig are slightly bigger (barrel for wire) than the one I have with my deutch connection kit I got online? Also using
supplied opposite end doesn't seem to lock the wires in as well as the kit I've used in the past for interior connections in the footwell. Fairly new to all this. Am I wrong in thinking there are different size barrels ? If so does anyone know the size Ineos uses. Hopefully this made sense
Thanks in advance

I did not cut the wires on the S2. I carefully disassembled the DT connector and was left with exposed wire to use for the DTP plug.

I did exactly this when installing my S2. Pretty straight forward as long as you got the right DTP plugs.
