Hello I’m the new one and have there also, how can it be different, immediately ask ne. But first a big praise for this forum here and because many members/helpers and your good answers. Now to the question: In the trunk left side is a storage compartment in this is located below a plug that does not answer anywhere can tell me what that is for? details about Omega: it is an Omega B Caravan from 09/98 dti voyage v94 no checkkontrol and no level regulation as far as I know otherwise not noticed. 🙂 Background is that I would like to build an AHK and I have read that under circumstances there is a preparation for it and I found this plug. Would I still have good recommendations for a detachable AHK and is it very difficult to install it myself? many thanks and greetings dti_voyage
