Backup Camera Hitch Plug

[jmarreroi]

Hi Guys:
I just bought a wireless transmitter for a backup camera to install in my 10' explorer, my plans are to install the camera inside the Hitch hole, but, I'm planning to take the transmitter elec. from the hitch plug. My question is, someone know what cable is the 12+ and where to make ground or - in this connector?

Thanks

If you have the four pin flat connector, you dont have a constant 12 volt + source, only a ground, tail light, left signal, and right signal. If you have a 7 pin round connector, you do have what you need and i believe + is about the 1 or 2 O'clock position but it should be marked on the cover.
