Just checked that connection - it was loose for some reason ??? - re-connected it and now she works. But, now it's throwing a p0706, transmission selector switch. Go figure, fix one, gain another! Any ideas on this?

How did you make out with this project?
Well - been driving my conversion for almost a year now, put about 13k on it. I couldn't be happier with the results - power is great and mileage is awesome, 12 around town and 18 on the freeway!
