Heated grips for FZ1 - recommendations???

[NorthWestern]

I removed a set of Oxford grips from my bike ( replacing damaged bars).  These ones were the larger, plastic hard ones that the previous owner had snipped the wires off. 


Is there a nack for removing them?  They seemed welded on and I had to slice them apart and use snips to.....snip the wire.  The clutch side was ok but trying to be more sympathetic on the throttle side I got skewered a couple of times by the snipped wires!
