I'm throwing this up as someone pointed out the wiring issues. Look at the bottom of the article and you'll see that on one conversion oil pressure switches were used to control the OD and lock up, essentially letting the trans itself select when for both.

here ya go.. you can buy the switches as a kit.. http://www.redrider.us/518_parts.htm
