Never changed a dresser but changed many softtail and it takes a little while to remove the controls and pull the wires threw the stock handle bars if they are already run internally ( have to pull the tank to get to the connector ( it's got a spec name of the connector, holds about 6 wires or so and their ind. numbered, their one for each side) under the tank and disconnect each wire in the connector and label them) then run the wires threw the new bars and mount them and reconnect the wires to the correct terminal on the connector,and reinstall the tank and hope everything works then, ( gotta be carfull not to pinch wires and ect. blew a couple of fuses in my day, but it is a job that is capable for some one semi skilled, but it does take time, 1st time I payed a local shop and watched him do it, and it took him a while, but after a few times ya pick up a few tricks,
