Right now I have a mini four strobe Whelen 9000. I want to convert it over to a 9M bar. Apparently it is not as easy as it looks. I know I need a 9M4S power supply in order to convert it but that's about all I know. Do I need an I/O board in order to plug the 6-pin plug into? If so, which I/O board? I plan to keep it a four strobe and add a piercer to the front and two halogen lights to the back as wig wags.
