Elinchrome flashes and Hasselblad X1DII

[KP]

Hi
I have an old set of Ranger Quadra RX Flashes and I wanted to use them the other day on a mini studio but I realized I couldn't as there is not sync plug on the X1DII and the remotes I have doen't work on the camera.
As it was a still subject I needed to shoot  and my room was quite dark, I managed to shoot it using a longer exposure time synchronizing the flash manually during that time but I need a cleaner configuration.
What remove should I get to get this work properly ?
Please excuse that quite candid question but due to the semi-lockdown in Paris, France, I can't ask my regular dealers (they are closed )
Thanks
Kristen

I have an elinchrom Quadra Hybrid, DL4 and Pro 1000 flashes it works fine alone or together with older Elinchrom Skyport speed or never Skyport Pro triggers mounted directly on the X1D hot shoe.
