Federal Signal Arjent SL High Side flasher wires

[Straypuft]

I have an Arjent(first gen I think) and wish to know before tearing it apart, It has signalmaster wires leading from the rear led modules, Are there enough wire leads from the rear flasher unit to turn those rear modules into regular rear flashing to match the rear outers and outer inboards that flash from the rear flasher?

If I need to make my own wire lead, What connectors do I need at the flasher side and the led module side?

I notice both high side flashers have 3 wires coming out of both channels connectors, But they run into a 12 connector block and I have no idea where to go from there.
