I've tried it on a same unit as yours. it does have voltage but doesn't work even after activating cruise on engine coding. My conclusion is it doesnt work for 2014 and below for Thailand made ECUs. Not totally sure unless I get a diagram for 2014 models. Note that when I tried putting up pins on those ports, The CAN BUS system TIMED out. luckily I was able to reset it.
Of course you can. But you'll need to "marry" that ECU to your unit. You have to reprogram everything related to Vehicle's unique identification and devices. I haven't tried that yet but it will surely involve flashing the new ECU with settings and values to be the same as the original. There is a VIN Changer in ETACS Decoder and MMCcoding and MUT. Haven explored that area yet but its 100% possible to DIY.
