@lurkist
Have totally overlooked your post for some reason. Thanks for the info, seems like it is the same scandoubler we are using.
Unfortunately, the previous owner of my scandoubler has fiddled around with the wires, and replaced them at some point (did a really {bleep}ty job at it unfortunately), so can you tell me to which hole on the scandoubler your red wire is connected to? (the hole towards the back of the motherboard, or the hole towards the front).
