So, I bought one of those $20 back-up camera's off of E-bay:

I have a cigarette lighter outlet in the back of my Highlander, so instead of tapping into an existing 12v wire and ground wire, I bought a cigarette lighter Y cable that you can just solder the camera's wires to, like this:

Well, when I turned my unit on, the little fuse part of the camera (circled in the picture) started burning. Does anyone have an idea as to what I did wrong?
I doubt I mixed up the positive and negative wires, but even if I did, it shouldn't have burned, right? The power input for the camera is a DC 12v 60MA.
Is there anyway for me to fix this without buying a new camera?
