I am still in hot pursuit for getting this done. I learned that the green wire from the wiper motor is the power lead. The green/yellow is for high speed and the brown for low speed. I am still trying to determine the other leads.(I think they be for a delay circuit) The mechanical set up is a little more vexing but also proceeding. My initial set up did not work but I am making modifications. It looks promising. When finished I will gladly share the results. I too have been dicouraged with the vacuum wipers and the cost of conversion kits. I got the wiper motor on ebay for $15. I expect conversion cost to be under $25.
