[QUOTE="DidUHearThat?, post: 5658541, member: 594758"] Another common mistake is forgetting to disconnet the battery while installing the H/U. The fuse blows (or worse) while making the connections. Check the fuse. Use your meter to make sure you have power at the H/U. Know which is switched and which is constant. If you know the H/U works. And you know you have 12v and a good ground, then double check your wiring, 'cus your doing something wrong. The problem is you. Draw out a schematic with all the wires labled coming from the car and into the H/U. That may clear it up. [/QUOTE]
