working on a 4350 project, past owners modified most of the wiring with xlr connectors. I have 4 wires left to hook up, they are orange/ orange/black and yellow/ yellow black. a little confused which might go to the 2405 and 2440 and polarity. I have the 2202 and 2231;s figured out. any past threads or help would be greatly appreciated. also any source for yellow insulation similar to the orginal. i could also use the lower clamp that bolts to the bracket for the 2440. thanks ktg
