Driving without an ABS lead connected

Might be a stupid question but can I ask does it work the otherway round … so if I send our our Volvo FH12 (early noughties) to collect a 1978 trailer from Belgium … will it work despite the tractor unit having ABS / EBS and the trailer (presuambly having none of these systems?). How does that work with VOSA … if the trailer is too old to have these systems fitted?

You don’t use the ABS lead just the Elec leads normal braking takes place no drama how do you think we got on pre ABS
