Wiper Motor Conversion

I have swapped my 3 spd wiper motor to a 2 spd on my 73 Duster so it wont interfere with Distributor. If I now buy a 2 spd switch is there a harness I can purchase to simply plug it all in or will I have to wire it. Not very good with wiring so prefer the harness option if available.
Do you have a picture of the final setup, I'm having a problem with not enough room by distributor and wondered if the 2 speed wiper motor gives you more room.
