FYI everyone, I finally found a Tin Lizzie dealer in OK (I'm in MO) who could order the wiring harness for the Queen Quilter for $75. Machine won't work w/o stitch regulator, s.r. plugs into machine & no way to run it w/o regulator as there is no where to plug in a foot control, if I had one. So, I guess I'm offering advice to anyone w this machine or thinking about buying a longarm, make sure the stitch regulator can be turned off, or unplugged from the machine and the machine will still operate. Expensive lesson learned, fasten cord so regulator cord can't be cut by wheels or connector attachment can't be broken, which mine was. Good quilting, everyone.
