I picked up an Ohio State Highway Patrol Vista bar a few weeks ago. The blue Man Down LED was disconnected from the Man Down PCB and wired to the main LED flasher. I would like to get it back to its original configuration but can't remember which connection is the positive and which is negative on the PCB board and I can't find anything from Federal Signal. The guy told me which was which and, thinking I was going to do it right away, I didn't write it down. I'm pretty sure they go to H1 and H4, just not sure which wire to which connection.
