I have the slow wiper problem in my 73 and my 1st solution was to change it out for one from an older parts car. Did that and found that it is different, no relay attached and the wiring colors are different on the harness and it runs at 1 speed as soon as the ignition is turned on. Doesn't matter where the wiper switch is set. Looking for help on that problem I found the Honda motor solution and wired it up to the relay using the diagram that Dave posted. All that happens is that the fuse blows. Any suggestions?? Graham
