Well, the good news is I get to keep the better sounding RX-18, bad news is now I'm really stuck. My KV-1 doesn't even have a switch, just some strips of metal, so placement of the 3 wires was trial and error. Realistically, the K button should not trigger the flash or IR, just the hull recoil and sound. Black wire from recoil motor was presoldered to the top post of the switch. The other 2 wires take the other legs and are in the only order that works when the switch is triggered. Where I stand at the moment is the K button, left stick and the micro switch all trigger the flash and IR when only the microswitch should.

Does anyone else have the new HL recoil unit from Phil?
