I'm going to rebuild an 8 head dominator bar (get a welder to make new end caps, rebuild the mangled screw shafts). I have a bunch of random model TIR3, and some LIN3/LIN4's I can use. About half the TIR3 have the typical 2 wire connector plugs, but most don't. Anyone know the wire gauge on a typical TIR3, OR, what model or type of plug Whelen uses? If not, anyone think I can get away with these? Wiring is 22 awg.
