...every mm extra space helps: I removed that connector, to get another mm of access-space. And as you can see I created another "special tool" to release the tension by using a "welded solid" 3/8 ratchet and a pipe extension to move the tensioner to the back of the car. There is not sufficient space for a normal ratchet, hence I used mine, which broke a long time ago and I welded the mechanism together (results in less height). HOWEVER, I saw meanwhile, that you do that normally from underneath
