Hi,
It took a while before i got answers on this on. Or the correct was that HD europe "refuse" to answer the quest they got from my dealer, when they checked for this internally.
Kory have the answer

order FLHTCUSE part #s55911-09a and 55913-09.
But as curious i was i had to check and verify for myself...
What we did was to go true the spare part book for SESG and FLTHCUSE and checked part by part. It was all the same except for the left end stub on the electronic throttle control. Then we checked the handlebar on the bike. On the first check earlier the dealer climbed after he have checked that the heater connector was NOT on the bike. What we did now was to dissemble the right handle bar to look closer and then we found that the connector was blended with a larger plastic cap 20mm instead for the small 10mm as normally. when we removed that it was all there

So to resume the conclusion: Order the FLTHCUSE heated handlebar if you can:) not as easy for all to order the original CVO heater as they require the vin no. The wiring is all complete on the right side, just remove the end cap on the throttle control and hook it on. On the left side there "are" enough space to pull the wire true, just work patient with it.
Org HD should then be bolt on... but as everything else expensice..
Heat demons are cheaper BUT it would weaken the handle bar, and why risk any critical situation ??
Just nice to know.....
