I want to put a USB car socket in the Lee room below between the steering wheel and the A-pillar and connect it to a flat fuse adapter for voltage absorption. Before I buy the two parts, I wanted to know how to get out the easiest way, how to put the fuse in. Before I buy the two parts, borrow a soldering iron or so cable quench connector and possibly a voltmeter. I want to be able to plug in my Navi and the K abel then to lay at the edge up to the disc before to the Navi. Ten years ago I had to deal with electrical engineering and soldered.
