Whelen LFL Power Supply Wiring

I'm looking for a wiring diagram for an LFL power supply... I did a quick search here with no results. Plus Whelen's site doesn't have a wiring diagram, just install sheet for the lightbar itself.


This is what I know:


red = power


black = ground


white = rear two strobes


grey = front two strobes


What I don't know is what the blue, green, brown & purple are...


Thanks in advance guys

If its a 412 supply.


Pink is positive and fused for 15amps.


Black is Negative.


Brown is flash pattern change, but you only have the choice of 2. One with the wire connected to positive and one with it disconnected.


Purple is low power mode.


Green goes to the I/o board. If connected to the I/o you gain a few more flash patterns for the strobes.


I can't remember what blue did. (it might be a sync for 2 supplies)

Since those things are so expensive, I was able to replace the mini ps with a couple


of sealed sound off power supplys. I used two sealed 2/40, actually boosting the


wattage from 15 watts per corner reflector to 20 watts per reflector, These power


supplys are the same height as the stock power supplys. You won't have the same mounting


such as the top frame mounting to the power supply, but once the lenses and the end


are on, its all stready and strong, I have done this with two mini lfls.

Yes, a serial controlled power supply doesn't require a serial controlled I/O board to operate, but it's flash pattern options are reduced to two.

Thanks..just not sure if I want to get and I/O board for this bar or not..$$$ is short
