You'd need a Wecan control board which, now that Wecan has been out for like a decade, shouldn't be too hard to come across. It would be a matter of just swapping them out and plugging in the lightheads. The Wecan board is 2-wire comms and 2-wire power. Real easy hookup to your Wecan controller.
And I say "shouldn't" be hard to find, because I'm surprised how some parts are difficult to come across despite being pretty common. One of the issues is this forum is pretty much the only one of its kind on the internet and with a relatively small readership, can sometimes be hard to find knick knacks like a Wecan board which are usually found at larger dealers and upfitters that can't be bothered with ELB.
