Why are you assuming I have a unit without instructions? For your info, I "do not" have a unit or instructions. Your remarks do nothing towards pointing me towards the DYI on this forum. You assume too much. I just want to read a DYI on installing a oil pressure sending unit on the new beetle car. If that is all right with you.
Easy Buddy! No character assasination intended, just looking for more information to maybe help you out. It was a logical assumption, you know; you're asking about it would lead one to believe you were wanting to install one. Are you wanting a DIY for a mechanical or electric oil pressure guage? Is it too presumtive to assume you have done an advanced thread search and/or a search of the Technical How-to Section?
Was your question, perhaps, more geared toward how to use the search features? That is the only way I know of to "point you towards" finding one without actually hunting for it myself and posting the link for you.
