I just bought a set of handlebars from a Heritage Softail to put on my Fatboy, I'm told the stock cables and wires will work fine. Can I just loosen the controls, slide them off then slide them on the new bars once installed? Or is it more involved, like disassembling the throttle assembly, etc?

 

that is exactly what i just did when i put some 2005 deuce bars on my 99 fxst. should be no reason to disconnect anything.
