Question about a 2007 Whelen Freedom wiring issue

[Scott Richard]

I recently purchased a couple of Whelen Freedom Lightbars that produced back in 2007. The Model Number is (Freedom "SC" NYSP) Serial Number is 25596. I am sure its just user error but I wanted to ask everyone here incase I was mission something. I was unable to find the correct wiring diagram for this lightbar and I am not sure if its the I/O Board or not. The cable colors im provided with are red and black as well as a smaller blue and purple. The lightbar is equipped with halogen alley and take down lights as well. When I connect power to each lighthead they light up steady burn but when I connect the power and ground wires directly to the battery I hear a "Click" but nothing on the lightbar works. All the connections that I can see are intact and all fuses in the I/O board are intact as well. Maybe im making a rookie mistake but hopefully someone on here can guide me in the right direction.


Thanks again

If I am not mistaken, SC means "serial controlled" and you need a controller such as the B-link system to get them to work.

This PDF would suggest that it is indeed a serial controlled bar and you need the B link controller. Second wire is likely gray, not purple
