ZEBRA51 0 Posted May 18, 2012 Yes, I know I have to wire red to + and black - , the problem is there are nine slots for + and another nine terminals for - , how do I determine where to wire. Share this post Link to post Share on other sites
Soundy 1 Posted May 18, 2012 Doesn't matter - just one pair of terminals per camera. Share this post Link to post Share on other sites
