The signals are from New Bonneville. He said they're in indefinite backorder and he'd never seen them used with the Throttle Boss. Kuryakyn said they don't carry heated grips and signal bar ends and that was it.
Just got back from my dealer (oh, that doesn't sound too good), he said they would work if you can get them, but they only work with ISO grips. So have decided to use the Rivco relocators and just move the signals down to the forks. Thanks again for your help.
