Have a stobe/halogen tomar lightbar. Not clear on how to power up the bar, seems to need a combination of wires to power up and I am not sure the combination.
Large RED: 12 volts direct battery w/40-50 amp circuit protection.
Large BLACK: Ground
Orange: Front of bar only (normally)
Orange and Blue together: Rear of bar only (normally)
Orange, Blue, White/black together: 360 degrees / intersections (normally)
Brown: takedown (if applicable)
Yellow: alley (if applicable)
Grey: alley (if applicable)
Blue by itself: directional arrow function (normally)
White/black by itself: directional arrow function (normally)
Blue and white/black together: directional arrow function (normally)
Green: Hi-Intensity wire (connect to 12 volts for Hi-Intensity)
red, white, brown/white: possible halogen fixture triggers.
Tomar bars could be configured in many ways, so you will need to trial and error your triggers to see what is what, but the above should get you started.
